No. 60/389,108, filed Jun. 14, 2002, and U.S. patent application Ser. No. 60/350,325, filed Jan. 18, 2002, all of which are herein incorporated by reference.

BACKGROUND OF THE INVENTION

[0002] Proliferation and differentiation of cells of multicellular organisms are controlled by hormones and polypeptide growth factors. These diffusable molecules allow cells to communicate with each other and act in concert to form cells, tissues and organs, and to repair damaged tissue. Examples of hormones and growth factors include the steroid hormones (e.g., estrogen, testosterone), parathyroid hormone, follicle stimulating hormone, the interleukins, platelet derived growth factor (PDGF), epidermal growth factor (EGF), granulocyte-macrophage colony stimulating factor (GM-CSF), erythropoietin (EPO) and calcitonin.

[0003] Hormones and growth factors influence cellular metabolism by binding to receptors. Receptors may be integral membrane proteins that are linked to signaling pathways within the cell, such as second messenger systems. Other classes of receptors are soluble molecules, such as the transcription factors.

[0004] Cytokines generally stimulate proliferation or differentiation of cells of the hematopoietic lineage or participate in the immune and inflammatory response mechanisms of the body. Examples of cytokines which affect hematopoiesis are erythropoietin (EPO), which stimulates the development of red blood cells; thrombopoietin (TPO), which stimulates development of cells of the megakaryocyte lineage; and granulocyte-colony stimulating factor (G-CSF), which stimulates development of neutrophils. These cytokines are useful in restoring normal blood cell levels in patients suffering from anemia, thrombocytopenia, and neutropenia or receiving chemotherapy for cancer.

[0005] The interleukins are a family of cytokines that mediate immunological responses, including inflammation. The interleukins mediate a variety of inflammatory pathologies. Central to an immune response are T cells, which produce many cytokines and adaptive immunity to antigens. Cytokines produced by T cells have been classified as type 1 and type 2 (Kelso, A. Immun. Cell Biol. 76:300-317, 1998). Type 1 cytokines include IL-2, IFN-γ, LT-α, and are involved in inflammatory responses, viral immunity, intracellular parasite immunity and allograft rejection. Type 2 cytokines include IL-4, IL-5, IL-6, IL-10 and IL-13, and are involved in humoral responses, helminth immunity and allergic response. Shared cytokines between Type 1 and 2 include IL-3, GM-CSF and TNF-α. There is some evidence to suggest that Type 1 and Type 2 producing T cell populations preferentially migrate into different types of inflamed tissue.

[0006] Mature T cells may be activated, i.e., by an antigen or other stimulus, to produce, for example, cytokines, biochemical signaling molecules, or receptors that further influence the fate of the T cell population.

[0007] B cells can be activated via receptors on their cell surface including B cell receptor and other accessory molecules to perform accessory cell functions, such as production of cytokines.

[0008] Monocytes/macrophages and T-cells can be activated by receptors on their cell surface and play a central role in the immune response by presenting antigen to lymphocytes and also act as accessory cells to lymphocytes by secreting numerous cytokines.

[0009] Natural killer (NK) cells have a common progenitor cell with T cells and B cells, and play a role in immune surveillance. NK cells, which comprise up to 15% of blood lymphocytes, do not express antigen receptors, and therefore do not use MHC recognition as requirement for binding to a target cell. NK cells are involved in the recognition and killing of certain tumor cells and virally infected cells. In vivo, NK cells are believed to require activation, however, in vitro, NK cells have been shown to kill some types of tumor cells without activation.

[0010] The demonstrated in vivo activities of these cytokines illustrate the enormous clinical potential of, and need for, other cytokines, cytokine agonists, and cytokine antagonists or binding partners. The present invention addresses these needs by providing a new hematopoietic multimeric cytokine receptor, as well as related compositions and methods.

[0011] The present invention provides such polypeptides for these and other uses that should be apparent to those skilled in the art from the teachings herein.

[0048] The present invention also provides a method for detecting a multiple cytokine receptor ligand from a test sample. The method includes contacting the test sample with a multimeric or heterodimeric cytokine receptor comprising a cytokine receptor polypeptide comprising amino acid residue 20 to amino acid residue 227 of SEQ ID NO: 111 and a cytokine-binding domain of a class I cytokine receptor; and detecting the binding of the multimeric or heterodimeric cytokine receptor to the ligand in the test sample.

DETAILED DESCRIPTION OF THE INVENTION

[0049] Definitions

[0050] Prior to setting forth the invention in detail, it may be helpful to the understanding thereof to define the following terms:

[0051] Unless otherwise specified, “a,” “an,” “the,” and “at least one” are used interchangeably and mean one or more than one.

[0052] The term “affinity tag” is used herein to denote a polypeptide segment that can be attached to a second polypeptide to provide for purification or detection of the second polypeptide or provide sites for attachment of the second polypeptide to a substrate. In principal, any peptide or protein for which an antibody or other specific binding agent is available can be used as an affinity tag. Affinity tags include a poly-histidine tract, protein A (Nilsson et al., EMBO J. 4:1075, 1985; Nilsson et al., Methods Enzymol. 198:3, 1991), glutathione S transferase (Smith and Johnson, Gene 67:31, 1988), Glu-Glu affinity tag (Grussenmeyer et al., Proc. Natl. Acad. Sci. USA 82:7952-4, 1985), substance P, Flag™ peptide (Hopp et al., Biotechnology 6:1204-10, 1988), streptavidin binding peptide, or other antigenic epitope or binding domain. See, in general, Ford et al., Protein Expression and Purification 2: 95-107, 1991. DNAs encoding affinity tags are available from commercial suppliers (e.g., Pharmacia Biotech, Piscataway, N.J.).

[0053] The term “allelic variant” is used herein to denote any of two or more alternative forms of a gene occupying the same chromosomal locus. Allelic variation arises naturally through mutation, and may result in phenotypic polymorphism within populations. Gene mutations can be silent (no change in the encoded polypeptide) or may encode polypeptides having altered amino acid sequence. The term allelic variant is also used herein to denote a protein encoded by an allelic variant of a gene.

[0054] The terms “amino-terminal” and “carboxyl-terminal” are used herein to denote positions within polypeptides. Where the context allows, these terms are used with reference to a particular sequence or portion of a polypeptide to denote proximity or relative position. For example, a certain sequence positioned carboxyl-terminal to a reference sequence within a polypeptide is located proximal to the carboxyl terminus of the reference sequence, but is not necessarily at the carboxyl terminus of the complete polypeptide.

[0055] The term “complement/anti-complement pair” denotes non-identical moieties that form a non-covalently associated, stable pair under appropriate conditions. For instance, biotin and avidin (or streptavidin) are prototypical members of a complement/anti-complement pair. Other exemplary complement/anti-complement pairs include receptor/ligand pairs, antibody/antigen (or hapten or epitope) pairs, sense/antisense polynucleotide pairs, and the like. Where subsequent dissociation of the complement/anti-complement pair is desirable, the complement/anti-complement pair preferably has a binding affinity of <10⁹M⁻¹.

[0056] The term “complements of a polynucleotide molecule” denotes a polynucleotide molecule having a complementary base sequence and reverse orientation as compared to a reference sequence. For example, the sequence 5′ ATGCACGGG 3′ is complementary to 5′ CCCGTGCAT 3′.

[0057] The term “contig” denotes a polynucleotide that has a contiguous stretch of identical or complementary sequence to another polynucleotide. Contiguous sequences are said to “overlap” a given stretch of polynucleotide sequence either in their entirety or along a partial stretch of the polynucleotide. For example, representative contigs to the polynucleotide sequence 5′-ATGGCTTAGCTT-3′ are 5′-TAGCTTgagtct-3′ and 3′-gtcgacTACCGA-5′.

[0058] The term “degenerate nucleotide sequence” denotes a sequence of nucleotides that includes one or more degenerate codons (as compared to a reference polynucleotide molecule that encodes a polypeptide). Degenerate codons contain different triplets of nucleotides, but encode the same amino acid residue (i.e., GAU and GAC triplets each encode Asp).

[0059] The term “expression vector” is used to denote a DNA molecule, linear or circular, that comprises a segment encoding a polypeptide of interest operably linked to additional segments that provide for its transcription. Such additional segments include promoter and terminator sequences, and may also include one or more origins of replication, one or more selectable markers, an enhancer, a polyadenylation signal, etc. Expression vectors are generally derived from plasmid or viral DNA, or may contain elements of both.

[0060] The term “isolated”, when applied to a polynucleotide, denotes that the polynucleotide has been removed from its natural genetic milieu and is thus free of other extraneous or unwanted coding sequences, and is in a form suitable for use within genetically engineered protein production systems. Such isolated molecules are those that are separated from their natural environment and include cDNA and genomic clones. Isolated DNA molecules of the present invention are free of other genes with which they are ordinarily associated, but may include naturally occurring 5′ and 3′ untranslated regions such as promoters and terminators. The identification of associated regions will be evident to one of ordinary skill in the art (see for example, Dynan and Tijan, Nature 316:774-78, 1985).

[0061] An “isolated” polypeptide or protein is a polypeptide or protein that is found in a condition other than its native environment, such as apart from blood and animal tissue. In a preferred form, the isolated polypeptide is substantially free of other polypeptides, particularly other polypeptides of animal origin. It is preferred to provide the polypeptides in a highly purified form, i.e. greater than 95% pure, more preferably greater than 99% pure. When used in this context, the term “isolated” does not exclude the presence of the same polypeptide in alternative physical forms, such as dimers or alternatively glycosylated or derivatized forms.

[0062] The term “neoplastic”, when referring to cells, indicates cells undergoing new and abnormal proliferation, particularly in a tissue where in the proliferation is uncontrolled and progressive, resulting in a neoplasm. The neoplastic cells can be either malignant, i.e., invasive and metastatic, or benign.

[0063] The term “operably linked”, when referring to DNA segments, indicates that the segments are arranged so that they function in concert for their intended purposes, e.g., transcription initiates in the promoter and proceeds through the coding segment to the terminator.

[0064] The term “ortholog” denotes a polypeptide or protein obtained from one species that is the functional counterpart of a polypeptide or protein from a different species. Sequence differences among orthologs are the result of speciation.

[0065] “Paralogs” are distinct but structurally related proteins made by an organism. Paralogs are believed to arise through gene duplication. For example, α-globin, β-globin, and myoglobin are paralogs of each other.

[0066] A “polynucleotide” is a single- or double-stranded polymer of deoxyribonucleotide or ribonucleotide bases read from the 5′ to the 3′ end. Polynucleotides include RNA and DNA, and may be isolated from natural sources, synthesized in vitro, or prepared from a combination of natural and synthetic molecules. Sizes of polynucleotides are expressed as base pairs (abbreviated “bp”), nucleotides (“nt”), or kilobases (“kb”). Where the context allows, the latter two terms may describe polynucleotides that are single-stranded or double-stranded. When the term is applied to double-stranded molecules it is used to denote overall length and will be understood to be equivalent to the term “base pairs”. It will be recognized by those skilled in the art that the two strands of a double-stranded polynucleotide may differ slightly in length and that the ends thereof may be staggered as a result of enzymatic cleavage; thus all nucleotides within a double-stranded polynucleotide molecule may not be paired.

[0067] A “polypeptide” is a polymer of amino acid residues joined by peptide bonds, whether produced naturally or synthetically. Polypeptides of less than about 10 amino acid residues are commonly referred to as “peptides”.

[0068] The term “promoter” is used herein for its art-recognized meaning to denote a portion of a gene containing DNA sequences that provide for the binding of RNA polymerase and initiation of transcription. Promoter sequences are commonly, but not always, found in the 5′ non-coding regions of genes.

[0069] A “protein” is a macromolecule comprising one or more polypeptide chains. A protein may also comprise non-peptidic components, such as carbohydrate groups. Carbohydrates and other non-peptidic substituents may be added to a protein by the cell in which the protein is produced, and will vary with the type of cell. Proteins are defined herein in terms of their amino acid backbone structures; substituents such as carbohydrate groups are generally not specified, but may be present nonetheless.

[0070] The term “receptor” denotes a cell-associated protein that binds to a bioactive molecule (i.e., a ligand) and mediates the effect of the ligand on the cell. Membrane-bound receptors are characterized by a multi-peptide structure comprising an extracellular ligand-binding domain and an intracellular effector domain that is typically involved in signal transduction. Binding of ligand to receptor results in a conformational change in the receptor that causes an interaction between the effector domain and other molecule(s) in the cell. This interaction in turn leads to an alteration in the metabolism of the cell. Metabolic events that are linked to receptor-ligand interactions include gene transcription, phosphorylation, dephosphorylation, increases in cyclic AMP production, mobilization of cellular calcium, mobilization of membrane lipids, cell adhesion, hydrolysis of inositol lipids and hydrolysis of phospholipids. In general, receptors can be membrane bound, cytosolic or nuclear; monomeric (e.g., thyroid stimulating hormone receptor, beta-adrenergic receptor) or multimeric (e.g., PDGF receptor, growth hormone receptor, IL-3 receptor, GM-CSF receptor, G-CSF receptor, erythropoietin receptor and IL-6 receptor).

[0071] The term “secretory signal sequence” denotes a DNA sequence that encodes a polypeptide (a “secretory peptide”) that, as a component of a larger polypeptide, directs the larger polypeptide through a secretory pathway of a cell in which it is synthesized. The larger polypeptide is commonly cleaved to remove the secretory peptide during transit through the secretory pathway.

[0072] A “soluble receptor” is a receptor polypeptide that is not bound to a cell membrane. Soluble receptors are most commonly ligand-binding receptor polypeptides that lack transmembrane and cytoplasmic domains. Soluble receptors can comprise additional amino acid residues, such as affinity tags that provide for purification of the polypeptide or provide sites for attachment of the polypeptide to a substrate, or immunoglobulin constant region sequences. Many cell-surface receptors have naturally occurring, soluble counterparts that are produced by proteolysis. Soluble receptor polypeptides are said to be substantially free of transmembrane and intracellular polypeptide segments when they lack sufficient portions of these segments to provide membrane anchoring or signal transduction, respectively.

[0073] The term “splice variant” is used herein to denote alternative forms of RNA transcribed from a gene. Splice variation arises naturally through use of alternative splicing sites within a transcribed RNA molecule, or less commonly between separately transcribed RNA molecules, and may result in several mRNAs transcribed from the same gene. Splice variants may encode polypeptides having altered amino acid sequence. The term splice variant is also used herein to denote a protein encoded by a splice variant of an mRNA transcribed from a gene.

[0074] Molecular weights and lengths of polymers determined by imprecise analytical methods (e.g., gel electrophoresis) will be understood to be approximate values. When such a value is expressed as “about” X or “approximately” X, the stated value of X will be understood to be accurate to ±10%.

[0075] The present invention is based in part upon the discovery of a novel multimeric cytokine receptor protein having the structure of a class I cytokine receptor, referred to herein as “multimeric cytokine receptor,” or “zcytor17 multimeric cytokine receptor.” The multimeric cytokine receptor includes at least a portion of a zcytor17 receptor subunit, disclosed in the commonly owned U.S. patent application Ser. No. 09/892,949. Another receptor subunit polypeptide that may be included in the multimeric cytokine receptor of the present invention includes at least a portion of at least one polypeptide of a class I cytokine receptor, such as OSMRbeta and/or WSX-1. For example, the deduced amino acid sequence indicated that zcytor17 belongs to the receptor subfamily that includes gp130, LIF, IL-12, oncostatinM receptor beta (OSMRbeta) (SEQ ID NO: 7), WSX-1 receptors (SEQ ID NO: 9) (Sprecher, C A et al., Biochem. Biophys. Res. Comm., 246:81-90 (1998); and U.S. Pat. No. 5,925,735), DCRS2 (WIPO Publication No. WO 00/73451), the IL-2 receptor β-subunit and the β-common receptor (i.e., IL-3, IL-5, and GM-CSF receptor subunits). A further example of class I cytokine receptor subunit polypeptides that may be included in the multimeric cytokine receptor are the receptors for IL-2, IL-4, IL-7, Lif, IL-12, IL-15, EPO, TPO, GM-CSF and G-CSF (Cosman, Cytokine, 5(2):95-106 (1993)).

[0076] Cytokine receptor subunits are characterized by a multi-domain structure comprising an extracellular domain, a transmembrane domain that anchors the polypeptide in the cell membrane, and an intracellular domain. The extracellular domain may be a ligand-binding domain, and the intracellular domain may be an effector domain involved in signal transduction, although ligand-binding and effector functions may reside on separate subunits of a multimeric receptor. The ligand-binding domain may itself be a multi-domain structure. Multimeric receptors include homodimers (e.g., PDGF receptor αα and ββ isoforms, erythropoietin receptor, MPL, and G-CSF receptor), heterodimers whose subunits each have ligand-binding and effector domains (e.g., PDGF receptor αβ isoform), and multimers having component subunits with disparate functions (e.g., IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, and GM-CSF receptors). Some receptor subunits are common to a plurality of receptors. For example, the AIC2B subunit, which cannot bind ligand on its own but includes an intracellular signal transduction domain, is a component of IL-3 and GM-CSF receptors. Many cytokine receptors can be placed into one of four related families on the basis of the structure and function. Hematopoietic receptors, for example, are characterized by the presence of a domain containing conserved cysteine residues and the WSXWS motif (SEQ ID NO: 3). Cytokine receptor structure has been reviewed by Urdal, Ann. Reports Med. Chem. 26:221-228, 1991 and Cosman, Cytokine 5:95-106, 1993. Under selective pressure for organisms to acquire new biological functions, new receptor family members likely arise from duplication of existing receptor genes leading to the existence of multi-gene families. Family members thus contain vestiges of the ancestral gene, and these characteristic features can be exploited in the isolation and identification of additional family members. Thus, the cytokine receptor superfamily is subdivided into several families, for example, the immunoglobulin family (including CSF-1, MGF, IL-1, and PDGF receptors); the hematopoietin family (including IL-2 receptor β-subunit, GM-CSF receptor α-subunit, GM-CSF receptor β-subunit; and G-CSF, EPO, IL-3, IL-4, IL-5, IL-6, IL-7, and IL-9 receptors); TNF receptor family (including TNF (p80) TNF (p60) receptors, CD27, CD30, CD40, Fas, and NGF receptor).

[0077] Analysis of the zcytor17 sequence suggests that it is a member of the same receptor subfamily as the gp130, LIF, IL-12, WSX-1, IL-2 receptor β-subunit, IL-3, IL-4, and IL-6 receptors. Certain receptors in this subfamily (e.g., G-CSF) associate to form homodimers that transduce a signal. Other members of the subfamily (e.g., gp130, IL-6, IL-11, and LIF receptors) combine with a second subunit (termed a β-subunit) to bind ligand and transduce a signal. Specific β-subunits associate with a plurality of specific cytokine receptor subunits. For example, the β-subunit gp130 (Hibi et al., Cell 63:1149-1157, 1990) associates with receptor subunits specific for IL-6, IL-11, and LIF (Gearing et al., EMBO J. 10:2839-2848, 1991; Gearing et al., U.S. Pat. No. 5,284,755). Oncostatin M binds to a heterodimer of LIF receptor and gp130. CNTF binds to trimeric receptors comprising CNTF receptor, LIF receptor, and gp130 subunits.

[0078] A multimeric cytokine receptor of the present invention can be a heterodimer, trimer, tetramer, pentamer, and the like, comprising at least a portion of zcytor17 and at least a portion of a class I cytokine receptor. In addition, a multimeric cytokine receptor can be soluble, membrane-bound, or attached to a solid support. Analysis of the tissue distribution of the mRNA of the zcytor17 receptor revealed expression in activated CD4+ and CD8+ T-cell subsets, CD14+ monocytes, and weaker expression in CD19+ B-cells. Moreover, the mRNA was present in both resting or activated monocytic cell lines THP-1 (ATCC No. TIB-202), U937 (ATCC No. CRL-1593.2) and HL60 (ATCC No. CCL-240).

[0079] Nucleotide sequences of representative zcytor17-encoding DNA are described in SEQ ID NO: 110 (from nucleotide 171 to 2366), with its deduced 732 amino acid sequence described in SEQ ID NO: 111; SEQ ID NO: 108 (from nucleotide 162 to 2108), with its deduced 649 amino acid sequence described in SEQ ID NO: 109; and in SEQ ID NO: 4 (from nucleotide 497 to 2482), with its deduced 662 amino acid sequence described in SEQ ID NO: 5. In its entirety, the zcytor17 polypeptide (SEQ ID NO: 111, SEQ ID NO: 109 or SEQ ID NO: 5) represents a full-length polypeptide segment (residue 1 (Met) to residue 732 (Val) of SEQ ID NO: 111; residue 1 (Met) to residue 649 (Ile) of SEQ ID NO: 109; residue 1 (Met) to residue 662 (Ile) of SEQ ID NO: 5). The domains and structural features of the zcytor17 polypeptides are further described below.

[0080] Analysis of the zcytor17 polypeptide encoded by the DNA sequence of SEQ ID NO: 110 revealed an open reading frame encoding 732 amino acids (SEQ ID NO: 111 ) comprising a predicted secretory signal peptide of 19 amino acid residues (residue 1 (Met) to residue 19 (Ala) of SEQ ID NO: 111), and a mature polypeptide of 713 amino acids (residue 20 (Ala) to residue 732 (Val) of SEQ ID NO: 111). Analysis of the zcytor17 polypeptide encoded by the DNA sequence of SEQ ID NO: 108 revealed an open reading frame encoding 649 amino acids (SEQ ID NO: 109) comprising a predicted secretory signal peptide of 19 amino acid residues (residue 1 (Met) to residue 19 (Ala) of SEQ ID NO: 109), and a mature polypeptide of 630 amino acids (residue 20 (Ala) to residue 649 (Ile) of SEQ ID NO: 109). Analysis of the zcytor17 polypeptide encoded by the DNA sequence of SEQ ID NO: 4 revealed an open reading frame encoding 662 amino acids (SEQ ID NO: 5) comprising a predicted secretory signal peptide of 32 amino acid residues (residue 1 (Met) to residue 32 (Ala) of SEQ ID NO: 5), and a mature polypeptide of 630 amino acids (residue 33 (Ala) to residue 662 (Ile) of SEQ ID NO: 5). In addition to the WSXWS motif (SEQ ID NO: 3) (corresponding to residues 211 to 215 of SEQ ID NO: 111 and SEQ ID NO: 109; and residues 224 to 228 of SEQ ID NO: 5), the receptor comprises an extracellular domain (residues 20 (Ala) to 519 (Glu) of SEQ ID NO: 111 and SEQ ID NO: 109; residues 33 (Ala) to 532 (Glu) of SEQ ID NO: 5) which includes a cytokine-binding domain of approximately 200 amino acid residues (residues 20 (Ala) to 227 (Pro) of SEQ ID NO: 111 and SEQ ID NO: 109; residues 33 (Ala) to 240 (Pro) of SEQ ID NO: 5); a domain linker (residues 122 (Thr) to 125 (Pro) of SEQ ID NO: 111 and SEQ ID NO: 109; residues 135 (Thr) to 138 (Pro) of SEQ ID NO: 111); a penultimate strand region (residues 194 (Phe) to 202 (Arg) of SEQ ID NO: 111and SEQ ID NO: 109; residues 207 (Phe) to 215 (Arg) of SEQ ID NO: 5); a fibronectin type III domain (residues 228 (Cys) to 519 (Glu) of SEQ ID NO: 111 and SEQ ID NO: 109; residues 241 (Cys) to 532 (Glu) of SEQ ID NO: 5); a transmembrane domain (residues 520 (Ile) 543 (Leu) of SEQ ID NO: 111 and SEQ ID NO: 109; residues 533 (Ile) to 556 (Leu) of SEQ ID NO: 5); complete intracellular signaling domain (residues 544 (Lys) to 732 (Val) of SEQ ID NO: 111; residues 544 (Lys) to 649 (Ile) of SEQ ID NO: 109; and residues 557 (Lys) to 662 (Ile) of SEQ ID NO: 5) which contains a “Box I” signaling site (residues 554 (Trp) to 560 (Pro) of SEQ ID NO: 111 and SEQ ID NO: 109; residues 567 (Trp) to 573 (Pro) of SEQ ID NO: 5), and a “Box II” signaling site (residues 617 (Gln) to 620 (Phe) of SEQ ID NO: 111 and SEQ ID NO: 109; residues 630 (Gln) to,633; (Phe) of SEQ ID NO: 5). Those skilled in the art will recognize that these domain boundaries are approximate, and are based on alignments with known proteins and predictions of protein folding. In addition to these domains, conserved receptor features in the encoded receptor include (as shown in SEQ ID NO: 111 and SEQ ID NO: 109) a conserved Cys residue at position 30 (position 43 as shown in SEQ ID NO: 5), CXW motif (wherein X is any amino acid) at positions 40-42 (positions 53-55, as shown in SEQ ID NO: 5), Trp residue at position 170 (position 183 as shown in SEQ ID NO: 5), and a conserved Arg residue at position 202 (position 215 as shown in SEQ ID NO: 5). The corresponding polynucleotides encoding the zcytor17 polypeptide regions, domains, motifs, residues and sequences described above are as shown in SEQ ID NO: 110, SEQ ID NO: 108, and SEQ ID NO: 4.

[0081] Moreover, truncated forms of the zcytor17 polypeptide appear to be naturally expressed. Both forms encode soluble zcytor17 receptors. A polynucleotide encoding a “long-form” of the soluble zcytor17 receptor, truncated within the fibronectin type III domain, is shown in SEQ ID NO: 112 and the corresponding polypeptide is shown in SEQ ID NO: 113. This truncated form encodes residues 1 (Met) through 324 (Lys) of SEQ ID NO: 111 and SEQ ID NO: 109), and thus comprises an intact signal sequence, WSXWS (SEQ ID NO: 3) motif, linker, cytokine binding domain, penultimate strand, and conserved, Cys, CXW motif, Trp and Arg residues as described above. A polynucleotide encoding a “short-form” of the soluble zcytor17 receptor, truncated at the end of the cytokine binding domain is shown in SEQ ID NO: 114 and the corresponding polypeptide is shown in SEQ ID NO: 115. This truncated form encodes a 239 residue polypeptide that is identical to residues 1 (Met) through 225 (Glu) of SEQ ID NO: 111 and SEQ ID NO: 109 and then diverges, and thus comprises an intact signal sequence, WSXWS (SEQ ID NO: 3) motif, linker, cytokine binding domain, penultimate strand, and conserved, Cys, CXW motif, Trp and Arg residues as described above. A multiple alignment of the truncated forms compared to the full-length forms of zcytor17 is shown in FIG. 1.

[0082] Moreover, the zcytor17 cDNA of SEQ ID NO: 110, SEQ ID NO: 108, SEQ ID NO: 112, and SEQ ID NO: 114 encode polypeptides that may use an alternative initiating methionine (at nucleotide 75 of SEQ If) NO: 110, at nucleotide 66 of SEQ ID NO: 108, at nucleotide 66 of SEQ ID NO: 112, and at nucleotide 66 of SEQ ID NO: 114) that would encode a polypeptide in the same open reading frame (ORF) as the zcytor17 polypeptides of SEQ ID NO: 111, SEQ ID NO: 109, SEQ ID NO: 113, and SEQ ID NO: 115. Use of the alternative initiating methionine would add 32 amino acids (shown in SEQ ID NO: 48) in-frame to the N-terminus of SEQ ID NO: 111, SEQ ID NO: 109, SEQ ID NO: 113, and SEQ ID NO: 111. In addition, nucleotide 536 of SEQ ID NO: 4 may serve as an alternative initiating methionine, thus generating the same N-terminus (starting at amino acid 14 (Met) of SEQ ID NO: 5) and signal polypeptide sequence, as SEQ ID NO: 111, SEQ ID NO: 109, SEQ ID NO: 113, and SEQ ID NO: 115. Moreover, the second Met at amino acid number 2 in the SEQ ID NO:111, SEQ ID NO: 109, SEQ ID NO: 113, and SEQ ID NO: 115 sequences (similarly at amino acid number 15 (Met) in SEQ ID NO: 5) may also serve as an alternative starting methionine for the polypeptides.

[0083] Nucleotide sequences of representative OSMRbeta-encoding DNA are described in SEQ ID NO: 6 (from nucleotide 368 to 3304), with its deduced 979 amino acid sequence described in SEQ ID NO: 7. In its entirety, the OSMRbeta polypeptide (SEQ ID NO: 7) represents a full-length polypeptide segment (residue 1 (Met) to residue 979 (Cys) of SEQ ID NO: 7. The domains and structural features of the OSMRbeta polypeptides are further described below.

[0084] Analysis of the OSMRbeta polypeptide encoded by the DNA sequence of SEQ ID NO: 6 revealed an open reading frame encoding 979 amino acids (SEQ ID NO: 7) comprising a predicted secretory signal peptide of 27 amino acid residues (residue 1 (Met) to residue 27 (Ala) of SEQ ID NO: 7), and a mature polypeptide of 952 amino acids (residue 28 (Glu) to residue 979. (Cys) of SEQ If) NO: 7. In addition to the two WSXWS motifs (SEQ ID NO: 3) (corresponding to residues 129 to 133 and residues 415 to 419 of SEQ ID NO: 7), the receptor comprises an extracellular domain (residues 28 (Glu) to 739 (Ser) of SEQ ID NO: 7); which includes a cytokine-binding domain of approximately 400 amino acid residues (residues 28 (Glu) to 429 (Ala) of SEQ ID NO: 7, which includes two linker domains (residues 31 (Pro) to 34 (Pro) and residues 343 (Asn) to 347 (Thr)), three regions of cytokine binding (residues 35 (Val) to 137 (Glu), residues 240 (Pro) to 342 (Glu), and residues 348 (Asn) to 429 (Ala), an immuglobulin domain (residues 138 (Val) to 239 (Glu), two penultimate strand regions (residues 106 (His) to 115 (Lys) and residues 398 (Thr) to 405 (Arg) of SEQ ID NO: 7), and a fibronectin type III domain (residues 430 (Pro) to 739 (Ser) of SEQ ID NO: 7); a transmembrane domain (residues 740 (Met) to 761 (Leu) of SEQ ID NO: 7); complete intracellular signaling domain (residues 762 (Lys) to 979 (Cys) of SEQ ID NO: 7) which contains a “Box I” signaling site (residues 771 (Tyr) to 777 (Pro) of SEQ ID NO: 7), and a “Box II” signaling site (residues 829 (Glu) to 832 (Leu) of SEQ ID NO: 7). Those skilled in the art will recognize that these domain boundaries are approximate, and are based on alignments with known proteins and predictions of protein folding. In addition to these domains, conserved receptor features in the encoded receptor include (as shown in SEQ ID NO: 7) conserved Trp residues at positions 52 and 353, a conserved Cys residue at position 288, CXW motif (wherein X is any amino acid) at positions 294-296, and a conserved Arg residue at position 405. The corresponding polynucleotides encoding the OSMRbeta polypeptide regions, domains, motifs, residues and sequences described above are as shown in SEQ ID NO: 6.

[0085] The presence of transmembrane regions, and conserved and low variance motifs generally correlates with or defines important structural regions in proteins. Regions of low variance (e.g., hydrophobic clusters) are generally present in regions of structural importance (Sheppard, P. et al., supra.). Such regions of low variance often contain rare or infrequent amino acids, such as Tryptophan. The regions flanking and between such conserved and low variance motifs may be more variable, but are often functionally significant because they may relate to or define important structures and activities such as binding domains, biological and enzymatic activity, signal transduction, cell-cell interaction, tissue localization domains and the like.

[0086] The regions of conserved amino acid residues in zcytor17, described above, can be used as tools to identify new family members. For instance, reverse transcription-polymerase chain reaction (RT-PCR) can be used to amplify sequences encoding the conserved regions from RNA obtained from a variety of tissue sources or cell lines. In particular, highly degenerate primers designed from the zcytor17 sequences are useful for this purpose. Designing and using such degenerate primers may be readily performed by one of skill in the art.

[0087] The present invention also contemplates a multimeric zcytor17 receptor, as detailed herein, which is capable of intracellular signaling. Such receptors may include at least a portion of at least one extracellular domain of a zcytor17 receptor, and an intracellular domain from a zcytor17 receptor or another class I cytokine receptor. In addition to the extracellular domain of zcytor17, the multimeric cytokine receptor can also include the extracellular domain of at least a portion of class I cytokine receptor, for instance, the ligand binding domains of OSMRbeta receptor and/or WSX-1 receptor. Alternatively, the multimeric cytokine receptor may include the extracellular domain of another receptor, such as another class I cytokine receptor, and the intracellular domain of zcytor17 to effect intracellular signaling.

[0088] The present invention further contemplates a multimeric cytokine receptor that is soluble. For example, a multimeric cytokine receptor may be, for instance, a heterodimer which includes, for example, a portion of the extracellular domain of zcytor17 and a portion of the extracellular domain of a class I cytokine receptor, such as OSMRbeta (SEQ ID NO: 7) and/or WSX-1 (SEQ ID NO: 9). Additionally, a soluble multimeric cytokine receptor may also include an affinity tag, such as an immuglobulin F_(c) polypeptide. The soluble multimeric cytokine receptor can be expressed as a fusion with an immunoglobulin heavy chain constant region, such as an F_(c) fragment, which contains two constant region domains and lacks the variable region. Such fusions are typically secreted as multimeric molecules wherein the F_(c) portions are disulfide bonded to each other and two non-Ig polypeptides are arrayed in closed proximity to each other. Fusions of this type can be used for example, for dimerization, increasing stability and in vivo half-life, to affinity purify ligand, as in vitro assay tool or antagonist.

[0089] Through processes of cloning, and proliferation assays described in detail herein, a multimeric cytokine receptor of the present invention has been shown to bind a novel ligand polypeptide (zcytor17lig) (SEQ ID NO: 2), disclosed in commonly owned U.S. patent application Ser. No. 60/350,325 and commonly owned U.S. patent application Ser. No. 60/375,323, with high specificity. Zcytor17lig was isolated from a cDNA library generated from activated human peripheral blood cells (hPBCs), which were selected for CD3. CD3 is a cell surface marker unique to cells of lymphoid origin, particularly T cells.

[0090] A zcytor17lig positive clone was isolated, and sequence analysis revealed that the polynucleotide sequence contained within the plasmid DNA was novel. The secretory signal sequence is comprised of amino acid residues 1 (Met) to 23 (Ala), and the mature polypeptide is comprised of amino acid residues 24 (Ser) to 164 (Thr) (as shown in SEQ ID NO: 2). Further, N-Terminal sequencing analysis of purified zcytor17lig from 293T cells showed an N-terminus at residue 27 (Leu) as shown in SEQ ID NO: 2, with the mature polypeptide comprised of amino acid residues 27 (Leu) to 164 (Thr) (as shown in SEQ ID NO: 2).

[0091] In general, cytokines are predicted to have a four-alpha helix structure, with helices A, C and D being most important in ligand-receptor interactions, and are more highly conserved among members of the family. Referring to the human zcytor17lig amino acid sequence shown in SEQ ID NO: 2, alignment of human zcytor17lig, human IL-3, and human cytokine amino acid sequences it is predicted that zcytor17lig helix A is defined by amino acid residues 38-52; helix B by amino acid residues 83-98; helix C by amino acid residues 104-117; and helix D by amino acid residues 137-152; as shown in SEQ ID NO: 2. Structural analysis suggests that the A/B loop is long, the B/C loop is short and the C/D loop is long. This loop structure results in an up-up-down-down helical organization. Based on 4-helix bundle structure, the cysteine residues within zcytor17lig that are conserved correspond to amino acid residues 72, 133, and 147 of SEQ ID NO: 2; and 74, 137, and 151 of SEQ ID NO: 11 described herein. Consistent cysteine placement is further confirmation of the four-helical-bundle structure. Also highly conserved in the zcytor17lig is the Glu residue as shown in SEQ ID NO: 2 at residue 43.

[0092] Moreover, the predicted amino acid sequence of murine zcytor17lig shows 31% identity to the predicted human protein over the entire length of the sequences (SEQ ID NO: 2 and SEQ ID NO: 11). Based on comparison between sequences of human and murine zcytor17lig conserved residues were found in the regions predicted to encode alpha helices C and D. The corresponding polynucleotides encoding the human zcytor17lig polypeptide regions, domains, motifs, residues and sequences described herein are as shown in SEQ ID NO: 1.

[0093] While helix D is relatively conserved between human and murine zcytor17lig, helix C is the most conserved. While both species have predominant acidic amino acids in this region, the differences may account for species specificity in interaction between zcytor17lig and its receptor, zcytor17, comprising monomeric, heterodimeric (e.g., zcytor17/OSMRbeta, WSX-1/OSMRbeta, zcytor17/WSX-1) or multimeric (e.g., zcytor17/OSMRbeta/WSX-1) receptors. Loop A/B and helix B of zcytor17lig are marginally conserved, and helix C through Loop C/D into helix D is most conserved between species; conservation through this region suggests that it is functionally significant. The D helices of human and murine zcytor17lig are also conserved. Zcytor17 receptor antagonists may be designed through mutations within zcytor17lig helix D. These may include truncation of the protein from residue Thr156 (SEQ ID NO: 2), or conservation of residues that confer binding of the ligand to the receptor, but diminish signaling activity.

[0094] Four-helical bundle cytokines are also grouped by the length of their component helices. “Long-helix” form cytokines generally consist of between 24-30 residue helices, and include IL-6, ciliary neutrotrophic factor (CNTF), leukemia inhibitory factor (LIF) and human growth hormone (hGH). “Short-helix” form cytokines generally consist of between 18-21 residue helices and include IL-2, IL-4 and GM-CSF. Zcytor17lig is believed to be a new member of the short-helix form cytokine group. Studies using CNTF and IL-6 demonstrated that a CNTF helix can be exchanged for the equivalent helix in IL-6, conferring CTNF-binding properties to the chimera. Thus, it appears that functional domains of four-helical cytokines are determined on the basis of structural homology, irrespective of sequence identity, and can maintain functional integrity in a chimera (Kallen et al., J. Biol. Chem. 274:11859-11867, 1999). Therefore, the helical domains of zcytor17lig may be useful for preparing chimeric fusion molecules, particularly with other short-helix form cytokines to determine and modulate receptor binding specificity. The present invention also envisions fusion proteins engineered with helix A and/or helix D, and fusion proteins that combine helical and loop domains from other short-form cytokines such as IL-2, IL-4, IL-15, Lif, IL-12, IL-3 and GM-CSF.

[0095] The polynucleotide sequence for human IL-2 is shown in SEQ ID NO: 176 and the corresponding amino acid sequence is shown in SEQ ID NO: 177. The secretory signal sequence is comprised of amino acid residues 1 (Met) to 20 (Ser) of SEQ ID NO: 177; nucleotides 48 to 107 of SEQ ID NO: 176. The mature polypeptide is comprised of amino acid residues 21 (Ala) to 156 (Thr) of SEQ ID NO: 177; nucleotides 108 to 515 of SEQ ID NO: 176. Helix A of human IL-2 is comprised of amino acid residues 27 (Thr) to 48 (Leu) of SEQ ID NO: 177; nucleotides 126 to 191 of SEQ ID NO: 176. Helix B of human IL-2 comprises Helix B1 and Helix B2. Helix B1 of human IL-2 is comprised of amino acid residues 73 (Ala) to 80 (Gln) of SEQ ID NO: 177; nucleotides 264 to 287 of SEQ ID NO: 176. Helix B2 of human IL-2 is comprised of amino acid residues 83 (Glu) to 92 (Val) of SEQ ID NO: 177; nucleotides 294 to 323 of SEQ ID NO: 176. Thus, Helix B (comprising Helices B1 and B2) of IL-2 is represented by the amino acid sequence of SEQ ID NO: 183 (nucleotide sequence of SEQ ID NO: 182) wherein amino acid residues 9 and 10 can be any amino acid. SEQ ID NO: 183 is identical to amino acids 73 (Ala) to 92 (Val) of SEQ ID NO: 177 wherein amino acids 81 and 82 are any amino acid. In a preferred form, Helix B of IL-2 comprises amino acids 73 (Ala) to 92 (Val) of SEQ ID NO: 177; nucleotides 264 to 323 of SEQ ID NO: 176. Helix C of human IL-2 is comprised of amino acid residues 102 (His) to 116 (Val) of SEQ ID NO: 177 nucleotides 351 to 395 of SEQ ID NO: 176. Helix D of human IL-2 is comprised of amino acid residues 134 (Thr) to 149 (Gln) of SEQ ID NO: 177; nucleotides 447 to 494 of SEQ ID NO: 176.

[0096] The polynucleotide sequence for human IL-4 is shown in SEQ ID NO: 178 and the corresponding amino acid sequence is shown in SEQ ID NO: 179. The secretory signal sequence is comprised of amino acid residues 1 (Met) to 24 (Gly) of SEQ ID NO: 179; nucleotides 64 to 135 of SEQ ID NO: 178. The mature polypeptide is comprised of amino acid residues 25 (His) to 153 (Ser) of SEQ ID NO: 179; nucleotides 136 to 522 of SEQ ID NO: 178. Helix A of human IL-4 is comprised of amino acid residues 30 (Thr) to 42 (Thr) of SEQ ID NO: 179; nucleotides 151 to 189 of SEQ ID NO: 178. Helix B of human IL-4 is comprised of amino acid residues 65 (Glu) to 83 (His) of SEQ ID NO: 179; nucleotides 256 to 312 of SEQ ID NO: 178. Helix C of human IL-4 is comprised of amino acid residues 94 (Ala) to 118 (Ala) of SEQ ID NO: 179; nucleotides 343 to 417 of SEQ ID NO: 178. Helix D of human IL-4 is comprised of amino acid residues 133 (Leu) to 151 (Cys) of SEQ ID NO: 179; nucleotides 460 to 516 of SEQ ID NO: 178.

[0097] The polynucleotide sequence for human GM-CSF is shown in SEQ ID NO: 180 and the corresponding amino acid sequence is shown in SEQ ID NO: 181. The secretory signal sequence is comprised of amino acid residues 1(Met) to 17 (Ser) of SEQ ID NO: 181; nucleotides 9 to 59 of SEQ ID NO: 180. The mature polypeptide is comprised of amino acid residues 18 (Ala) to 144 (Glu) of SEQ ID NO: 181; nucleotides 60 to 440 of SEQ ID NO: 180.

[0098] The amino acid residues comprising helices A, B, C, and D, for human zcytor17lig, IL-3, IL-2, IL-4, and GM-CSF are shown in Table 1.

[0099] The present invention provides polynucleotide molecules, including DNA and RNA molecules that encode the zcytor17 polypeptides disclosed herein that can be included in the multimeric cytokine receptor. Those skilled in the art will recognize that, in view of the degeneracy of the genetic code, considerable sequence variation is possible among these polynucleotide molecules. SEQ ID NO: 120, SEQ ID NO: 121 and SEQ ID NO: 122 are degenerate DNA sequences that encompass all DNAs that encode the zcytor17 polypeptide of SEQ ID NO: 111, SEQ ID NO: 109 and SEQ ID NO: 5, respectively, and fragments thereof. Those skilled in the art will recognize that the degenerate sequences of SEQ ID NO: 120, SEQ ID NO: 121 and SEQ ID NO: 122 also provide all RNA sequences encoding SEQ ID NO: 111, SEQ ID NO: 109 and SEQ ID NO: 5 by substituting U for T. Thus, zcytor17,polypeptide-encoding polynucleotides comprising nucleotide 1 to nucleotide 2196 of SEQ ID NO: 120, nucleotide 1 to nucleotide 1947 of SEQ ID NO: 121, and nucleotide 1 to nucleotide 1986 of SEQ ID NO: 122 and their RNA equivalents are contemplated by the present invention. Table 2 sets forth the one-letter codes used within SEQ ID NO: 120, SEQ ID NO: 121 and SEQ ID NO: 122 to denote degenerate nucleotide positions. “Resolutions” are the nucleotides denoted by a code letter. “Complement” indicates the code for the complementary nucleotide(s). For example, the code Y denotes either C or T, and its complement R denotes A or G, A being complementary to T, and G being complementary to C.

[0100] The degenerate codons used in SEQ ID NO: 120, SEQ ID NO: 121 and SEQ ID NO: 122, encompassing all possible codons for a given amino acid, are set forth in Table 3.

[0101] One of ordinary skill in the art will appreciate that some ambiguity is introduced in determining a degenerate codon, representative of all possible codons encoding each amino acid. For example, the degenerate codon for serine (WSN) can, in some circumstances, encode arginine (AGR), and the degenerate codon for arginine (MGN) can, in some circumstances, encode serine (AGY). A similar relationship exists between codons encoding phenylalanine and leucine. Thus, some polynucleotides encompassed by the degenerate sequence may encode variant amino acid sequences, but one of ordinary skill in the art can easily identify such variant sequences by reference to the amino acid sequences of SEQ ID NO: 111, SEQ ID NO: 109 and SEQ ID NO: 5; or SEQ ID NO: 117 and SEQ ID NO: 119. Variant sequences can be readily tested for functionality as described herein.

[0102] One of ordinary skill in the art will also appreciate that different species can exhibit “preferential codon usage.” In general, see, Grantham, et al., Nuc. Acids Res. 8:1893-912, 1980; Haas, et al. Curr. Biol. 6:315-24, 1996; Wain-Hobson et al., Gene 13:355-64, 1981; Grosjean and Fiers, Gene 18:199-209, 1982; Holm, Nuc. Acids Res. 14:3075-87, 1986; Ikemura, J. Mol. Biol. 158:573-97, 1982. As used herein, the term “preferential codon usage” or “preferential codons” is a term of art referring to protein translation codons that are most frequently used in cells of a certain species, thus favoring one or a few representatives of the possible codons encoding each amino acid (See Table 3). For example, the amino acid Threonine (Thr) may be encoded by ACA, ACC, ACG, or ACT, but in mammalian cells ACC is the most commonly used codon; in other species, for example, insect cells, yeast, viruses or bacteria, different Thr codons may be preferential. Preferential codons for a particular species can be introduced into the polynucleotides of the present invention by a variety of methods known in the art. Introduction of preferential codon sequences into recombinant DNA can, for example, enhance production of the protein by making protein translation more efficient within a particular cell type or species. Therefore, the degenerate codon sequences disclosed in SEQ ID NO: 120, SEQ ID NO: 121 and SEQ ID NO: 122 serve as templates for optimizing expression of zcytor17 polynucleotides in various cell types and species commonly used in the art and disclosed herein. Sequences containing preferential codons can be tested and optimized for expression in various species, and tested for functionality as disclosed herein.

[0103] As previously noted, the isolated polynucleotides of the present invention include DNA and RNA. Methods for preparing DNA and RNA are well known in the art. In general, RNA is isolated from a tissue or cell that produces large amounts of zcytor17 RNA. Such tissues and cells are identified by Northern blotting (Thomas, Proc. Natl. Acad. Sci. USA 77:5201, 1980), and include PBLs, spleen, thymus, bone marrow, prostate, and lymph tissues, human erythroleukemia cell lines, acute monocytic leukemia cell lines, other lymphoid and hematopoietic cell lines, and the like. Total RNA can be prepared using guanidinium isothiocyanate extraction followed by isolation by centrifugation in a CsCl gradient (Chirgwin et al., Biochemistry 18:52-94, 1979). Poly (A)⁺ RNA is prepared from total RNA using the method of Aviv and Leder (Proc. Natl. Acad. Sci. USA 69:1408-12, 1972). Complementary DNA (cDNA) is prepared from poly(A)⁺ RNA using known methods. In the alternative, genomic DNA can be isolated. Polynucleotides encoding zcytor17 polypeptides are then identified and isolated by, for example, hybridization or polymerase chain reaction (PCR) (Mullis, U.S. Pat. No. 4,683,202).

[0104] A full-length clone encoding zcytor17 can be obtained by conventional cloning procedures. Complementary DNA (cDNA) clones are preferred, although for some applications (e.g., expression in transgenic animals) it may be preferable to use a genomic clone, or to modify a cDNA clone to include at least one genomic intron. Methods for preparing cDNA and genomic clones are well known and within the level of ordinary skill in the art, and include the use of the sequence disclosed herein, or parts thereof, for probing or priming a library. Expression libraries can be probed with antibodies to zcytor17, receptor fragments, or other specific binding partners.

[0105] The polynucleotides of the present invention can also be synthesized using DNA synthesis machines. Currently the method of choice is the phosphoramidite method. If chemically synthesized double stranded DNA is required for an application such as the synthesis of a gene or a gene fragment, then each complementary strand is made separately. The production of short polynucleotides (60 to 80 bp) is technically straightforward and can be accomplished by synthesizing the complementary strands and then annealing them. However, for producing longer polynucleotides (>300 bp), special strategies are usually employed, because the coupling efficiency of each cycle during chemical DNA synthesis is seldom 100%. To overcome this problem, synthetic genes (double-stranded) are assembled in modular form from single-stranded fragments that are from 20 to 100 nucleotides in length.

[0106] An alternative way to prepare a full-length gene is to synthesize a specified set of overlapping oligonucleotides (40 to 100 nucleotides). After the 3′ and 5′ short overlapping complementary regions (6 to 10 nucleotides) are annealed, large gaps still remain, but the short base-paired regions are both long enough and stable enough to hold the structure together. The gaps are filled and the DNA duplex is completed via enzymatic DNA synthesis by E. coli DNA polymerase I. After the enzymatic synthesis is completed, the nicks are sealed with T4 DNA ligase. Double-stranded constructs are sequentially linked to one another to form the entire gene sequence which is verified by DNA sequence analysis. See Glick and Pasternak, Molecular Biotechnology, Principles & Applications of Recombinant DNA, (ASM Press, Washington, D.C. 1994); Itakura et al., Annu. Rev. Biochem. 53: 323-56, 1984 and Climie et al., Proc. Natl. Acad. Sci. USA 87:633-7, 1990. Moreover, other sequences are generally added that contain signals for proper initiation and termination of transcription and translation.

[0107] The present invention also provides reagents which will find use in diagnostic applications. For example, the zcytor17lig gene, a probe comprising zcytor17lig DNA or RNA or a subsequence thereof, can be used to determine if the zcytor17lig gene is present on a human chromosome, such as chromosome 12, or if a gene mutation has occurred. Zcytor17lig is located at the 12q24.31 region of chromosome 12 (Example 13). Detectable chromosomal aberrations at the zcytor17lig gene locus include, but are not limited to, aneuploidy, gene copy number changes, loss of heterozygosity (LOH), translocations, insertions, deletions, restriction site changes and rearrangements. Such aberrations can be detected using polynucleotides of the present invention by employing molecular genetic techniques, such as restriction fragment length polymorphism (RFLP) analysis, short tandem repeat (STR) analysis employing PCR techniques, and other genetic linkage analysis techniques known in the art (Sambrook et al., ibid.; Ausubel et. al., ibid.; Marian, Chest 108:255-65, 1995).

[0108] The precise knowledge of a gene's position can be useful for a number of purposes, including: 1) determining if a sequence is part of an existing contig and obtaining additional surrounding genetic sequences in various forms, such as YACs, BACs or cDNA clones; 2) providing a possible candidate gene for an inheritable disease which shows linkage to the same chromosomal region; and 3) cross-referencing model organisms, such as mouse, which may aid in determining what function a particular gene might have.

[0109] One of skill in the art would recognize that the 12q24 region is frequently involved in gross genomic rearrangements, including translocations, deletions, inversions, and duplications, that are associated with various cancers. The Mitelman Database of Chromosomal Aberrations in Cancer, at the Cancer Genome Anatomy Project, National Insitutes of Health, Bethesda, Md. located on the Internet lists 199 cases of cancers with genomic rearrangements involving 12q24. Of these, most are part of complex karyotypes with other rearrangements; however, in some cases the rearrangement involving 12q24 is the only genomic alteration. Given the expression of the receptor for zcytor17lig on cells of lymphoid and myeloid lineages, it is particularly significant to note that there are at least 4 cases of myeloid leukemia reported in the literature in which either translocation (2 cases: Yamagata et al, Cancer Genet Cytogenet 97:90-93, 1997; Dunphy and Batanian, Cancer Genet Cytogenet 114:51-57, 1999) or duplication (2 cases: Bonomi et al, Cancer Genet Cytogenet 108:75-78, 1999) are the sole genomic alteration. This suggests that a gene or genes residing within 12q24 could be directly involved in the malignant transformation of these patients' cells. Inappropriate over expression of zcytor17lig could contribute to malignant transformation by promoting aberrant proliferation of receptor-bearing cells, through either autocrine or paracrine mechanisms. Inhibition of zcytor17lig activity could thus inhibit growth of such cells. Alternatively, a genomic rearrangement resulting in inactivation of the zcytor17lig gene may promote malignant transformation and/or metastasis by removing zcytor17lig immunoregulatory functions. Indeed, a gene suppressing metastasis in prostate cancer has been mapped to 12q24-qter (Ichikawa et al, Asian J Androl 2:167-171, 2000). If zcytor17lig is the gene within this region responsible for the suppression of metastasis, then zcytor17lig itself may have therapeutic value in the treatment of cancer.

[0110] A diagnostic could assist physicians in determining the type of disease and appropriate associated therapy, or assistance in genetic counseling. As such, the inventive anti-zcytor17lig antibodies, polynucleotides, and polypeptides can be used for the detection of zcytor17lig polypeptide, mRNA or anti-zcytor17lig antibodies, thus serving as markers and be directly used for detecting or genetic diseases or cancers, as described herein, using methods known in the art and described herein. Further, zcytor17lig polynucleotide probes can be used to detect abnormalities or genotypes associated with chromosome 12q24.3 deletions and translocations associated with human diseases, or other translocations involved with malignant progression of tumors or other 12q24.3 mutations, which are expected to be involved in chromosome rearrangements in malignancy; or in other cancers. Similarly, zcytor17lig polynucleotide probes can be used to detect abnormalities or genotypes associated with chromosome 12 trisomy and chromosome loss associated with human diseases or spontaneous abortion. Thus, zcytor17lig polynucleotide probes can be used to detect abnormalities or genotypes associated with these defects.

[0111] One of skill in the art would recognize that zcytor17lig polynucleotide probes are particularly useful for diagnosis of gross chromosomal abnormalities associated with loss of heterogeneity (LOH), chromosome gain (e.g., trisomy), translocation, DNA amplification, and the like. Translocations within chromosomal locus 12q24.3 wherein the zcytor17lig gene is located are known to be associated with human disease. For example, 12q24 deletions and translocations, duplications and trisomy are associated with cancers as discussed above. Thus, since the zcytor17lig gene maps to this critical region, zcytor17lig polynucleotide probes of the present invention can be used to detect abnormalities or genotypes associated with 12q24 translocation, deletion and trisomy, and the like, described above.

[0112] As discussed above, defects in the zcytor17lig gene itself may result in a heritable human disease state. Molecules of the present invention, such as the polypeptides, antagonists, agonists, polynucleotides and antibodies of the present invention would aid in the detection, diagnosis prevention, and treatment associated with a zcytor17lig genetic defect. In addition, zcytor17lig polynucleotide probes can be used to detect allelic differences between diseased or non-diseased individuals at the zcytor17lig chromosomal locus. As such, the zcytor17lig sequences can be used as diagnostics in forensic DNA profiling.

[0113] In general, the diagnostic methods used in genetic linkage analysis, to detect a genetic abnormality or aberration in a patient, are known in the art. Analytical probes will be generally at least 20 nt in length, although somewhat shorter probes can be used (e.g., 14-17 nt). PCR primers are at least 5 nt in length, preferably 15 or more, more preferably 20-30 nt. For gross analysis of genes, or chromosomal DNA, a zcytor17lig polynucleotide probe may comprise an entire exon or more. Exons are readily determined by one of skill in the art by comparing zcytor17lig sequences (SEQ ID NO: 1) with the genomic DNA for mouse zcytor17lig (SEQ ID NO: 76). In general, the diagnostic methods used in genetic linkage analysis, to detect a genetic abnormality or aberration in a patient, are known in the art. Most diagnostic methods comprise the steps of (a) obtaining a genetic sample from a potentially diseased patient, diseased patient or potential non-diseased carrier of a recessive disease allele; (b) producing a first reaction product by incubating the genetic sample with a zcytor17lig polynucleotide probe wherein the polynucleotide will hybridize to complementary polynucleotide sequence, such as in RFLP analysis or by incubating the genetic sample with sense and antisense primers in a PCR reaction under appropriate PCR reaction conditions; (iii) visualizing the first reaction product by gel electrophoresis and/or other known methods such as visualizing the first reaction product with a zcytor17lig polynucleotide probe wherein the polynucleotide will hybridize to the complementary polynucleotide sequence of the first reaction; and (iv) comparing the visualized first reaction product to a second control reaction product of a genetic sample from wild type patient, or a normal or control individual. A difference between the first reaction product and the control reaction product is indicative of a genetic abnormality in the diseased or potentially diseased patient, or the presence of a heterozygous recessive carrier phenotype for a non-diseased patient, or the presence of a genetic defect in a tumor from a diseased patient, or the presence of a genetic abnormality in a fetus or pre-implantation embryo. For example, a difference in restriction fragment pattern, length of PCR products, length of repetitive sequences at the zcytor17lig genetic locus, and the like, are indicative of a genetic abnormality, genetic aberration, or allelic difference in comparison to the normal wild type control. Controls can be from unaffected family members, or unrelated individuals, depending on the test and availability of samples. Genetic samples for use within the present invention include genomic DNA, mRNA, and cDNA isolated from any tissue or other biological sample from a patient, which includes, but is not limited to, blood, saliva, semen, embryonic cells, amniotic fluid, and the like. The polynucleotide probe or primer can be RNA or DNA, and will comprise a portion of SEQ ID NO: 1, the complement of SEQ ID NO: 1, or an RNA equivalent thereof. Such methods of showing genetic linkage analysis to human disease phenotypes are well known in the art.

[0114] Mutations associated with the zcytor17lig locus can be detected using nucleic acid molecules of the present invention by employing standard methods for direct mutation analysis, such as restriction fragment length polymorphism analysis, short tandem repeat analysis employing PCR techniques, amplification-refractory mutation system analysis, single-strand conformation polymorphism detection, RNase cleavage methods, denaturing gradient gel electrophoresis, fluorescence-assisted mismatch analysis, and other genetic analysis techniques known in the art (see, for example, Mathew (ed.), Protocols in Human Molecular Genetics (Humana Press, Inc. 1991), Marian, Chest 108:255 (1995), Coleman and Tsongalis, Molecular Diagnostics (Human Press, Inc. 1996), Elles (ed.)

Direct analysis of an zcytor17lig gene for a mutation can be performed using a subject's genomic DNA. Methods for amplifying genomic DNA, obtained for example from peripheral blood lymphocytes, are well-known to those of skill in the art (see, for example, Dracopoli et al. (eds.), Current Protocols in Human Genetics, at pages 7.1.6 to 7.1.7 (John Wiley & Sons 1998)).

[0115] The present invention further provides counterpart polypeptides and polynucleotides from other species (orthologs). These species include, but are not limited to mammalian, avian, amphibian, reptile, fish, insect and other vertebrate and invertebrate species. Of particular interest are zcytor17 polypeptides from other mammalian species, including murine, porcine, ovine, bovine, canine, feline, equine, and other primate polypeptides. Orthologs of human zcytor17 can be cloned using information and compositions provided by the present invention in combination with conventional cloning techniques. For example, a cDNA can be cloned using mRNA obtained from a tissue or cell type that expresses zcytor17 as disclosed herein. Suitable sources of mRNA can be identified by probing Northern blots with probes designed from the sequences disclosed herein. A library is then prepared from mRNA of a positive tissue or cell line. A zcytor17-encoding cDNA can then be isolated by a variety of methods, such as by probing with a complete or partial human cDNA or with one or more sets of degenerate probes based on the disclosed sequences. A cDNA can also be cloned using PCR (Mullis, supra.), using primers designed from the representative human zcytor17 sequence disclosed herein. Within an additional method, the cDNA library can be used to transform or transfect host cells, and expression of the cDNA of interest can be detected with an antibody to zcytor17 polypeptide. Similar techniques can also be applied to the isolation of genomic clones.

[0116] A polynucleotide sequence for the mouse ortholog of human zcytor17 has been identified and is shown in SEQ ID NO: 116 and the corresponding amino acid sequence shown in SEQ ID NO: 117. Analysis of the mouse zcytor17 polypeptide encoded by the DNA sequence of SEQ ID NO: 116 revealed an open reading frame encoding 662 amino acids (SEQ ID NO: 117) comprising a predicted secretory signal peptide of 45 amino acid residues (residue 1 (Met) to residue 45 (Ala) of SEQ ID NO: 117), and a mature polypeptide of 617 amino acids (residue46 (Val) to residue 662 (Cys) of SEQ ID NO: 117). Moreover, an additional Met residue, Met (28) can be used as a starting methionine; comprising a second predicted secretory signal peptide of 18 amino acid residues (residue 28 (Met) to residue 45 (Ala) of SEQ ID NO: 117), and the same mature polypeptide of 617 amino acids (residue46 (Val) to residue 662 (Cys) of SEQ ID NO: 117. In addition to the WSXWS motif (SEQ ID NO: 3) corresponding to residues 224-228 of SEQ ID NO: 117, the receptor comprises an extracellular domain from residues 46 (Val) to 533 (Glu) of SEQ ID NO: 117) that includes a cytokine-binding domain of approximately 200 amino acid residues (residues 46 (Val) to 240 (Pro) of SEQ ID NO: 117) and a fibronectin III domain (residues 241 (His) to 533 (Glu) of SEQ ID NO: 117); a CXW motif (residues 66 (Cys) to 68 (Trp) of SEQ ID NO: 117); a domain linker (residues 142 (Thr) to 145 (Pro) of SEQ ID NO: 117); a penultimate strand region (residues 207 (Phe) to 215 (Arg) of SEQ ID NO: 117); a transmembrane domain (residues 534 (Ile) to 550 (Ile) of SEQ ID NO: 117); complete intracellular signaling domain (residues 551 (Lys) to 662 (Cys) of SEQ ID NO: 117) which contains a “Box I” signaling site (residues 568 (Cys) to 574 (Pro) of SEQ ID NO: 117), and a “Box II” signaling site (residues 628 (Glu) to 631 (leu) of SEQ ID NO: 117). Conserved residues common to class I cytokine receptors, are at residues 56 (Cys), 187 (Trp), and 215 (Arg). A comparison of the human and mouse amino acid sequences reveals that both the human and orthologous polypeptides contain corresponding structural features described above (and, see, FIG. 2). The mature sequence for the mouse zcytor17 begins at Val₄₆ (as shown in SEQ ID NO: 117), which corresponds to Ala₃₃ (as shown in SEQ ID NO: 5) in the human sequence. There is about 61% identity between the mouse and human sequences over the entire amino acid sequence corresponding to SEQ ID NO: 5 and SEQ ID NO: 117. The above percent identity was determined using a FASTA program with ktup=1, gap opening penalty=12, gap extension penalty=2, and substitution matrix=BLOSUM62, with other parameters set as default. The corresponding polynucleotides encoding the mouse zcytor17 polypeptide regions, domains, motifs, residues and sequences described above are as shown in SEQ ID NO: 116.

[0117] Moreover, a truncated soluble form of the mouse zcytor17 receptor polypeptide appears to be naturally expressed. A polynucleotide sequence for a truncated soluble form of the mouse zcytor17 receptor has been identified and is shown in SEQ ID NO: 118 and the corresponding amino acid sequence shown in SEQ ID NO: 119. Analysis of the truncated soluble mouse zcytor17 polypeptide encoded by the DNA sequence of SEQ ID NO: 118 revealed an open reading frame encoding 547 amino acids (SEQ ID NO: 119) comprising a predicted secretory signal peptide of 45 amino acid residues (residue 1 (Met) to residue 45 (Ala) of SEQ ID NO: 119), and a mature polypeptide of 502 amino acids (residue46 (Val) to residue 547 (Val) of SEQ ID NO: 119). Moreover, an additional Met residue, Met (28) can be used as a starting methionine; comprising a second predicted secretory signal peptide of 18 amino acid residues (residue 28 (Met) to residue 45 (Ala) of SEQ ID NO: 119), and the same mature polypeptide of 502 amino acids (residue46 (Val) to residue 547 (Val) of SEQ ID NO: 119. In addition to the WSXWS motif (SEQ ID NO: 3) corresponding to residues 224-228 of SEQ ID NO: 119, the receptor comprises an extracellular domain from residues 46 (Val) to 533 (Trp) of SEQ ID NO: 119) that includes a cytokine-binding domain of approximately 200 amino acid residues (residues 46 (Val) to 240 (Pro) of SEQ ID NO: 119) and a fibronectin III domain (residues 241 (His) to 533 (Trp) of SEQ ID NO: 119); a CXW motif (residues 66 (Cys) to 68 (Trp) of SEQ ID NO: 119); a domain linker (residues 142 (Thr) to 145 (Pro) of SEQ ID NO: 119); a penultimate strand region (residues 207 (Phe) to 215 (Arg) of SEQ ID NO: 119); and a C-terminal tail region (residues 534 (Leu) to 547 (Val). Conserved residues common to class I cytokine receptors, are at residues 56 (Cys), 187 (Trp), and 215 (Arg). A comparison of the human and mouse amino acid sequences, including the truncated soluble mouse zcytor17, reveals that both the human and orthologous polypeptides contain corresponding structural features described above (and, see, FIG. 2). The corresponding polynucleotides encoding the truncated soluble mouse zcytor17 polypeptide regions, domains, motifs, residues and sequences described above are as shown in SEQ ID NO: 118.

[0118] Those skilled in the art will recognize that the sequences disclosed in SEQ ID NO: 110, SEQ ID NO: 108 and SEQ ID NO: 4 represent alleles of human zcytor17 and that allelic variation and alternative splicing are expected to occur. Allelic variants of this sequence can be cloned by probing cDNA or genomic libraries from different individuals according to standard procedures. Allelic variants of the DNA sequence shown in SEQ ID NO: 110, SEQ ID NO: 108 or SEQ ID NO: 4, including those containing silent mutations and those in which mutations result in amino acid sequence changes, are within the scope of the present invention, as are proteins which are allelic variants of SEQ ID NO: 111, SEQ ID NO: 109, SEQ ID NO: 5 SEQ ID NO: 117 or SEQ ID NO: 119. cDNAs generated from alternatively spliced mRNAs, which retain the properties of the zcytor17 polypeptide are included within the scope of the present invention, as are polypeptides encoded by such cDNAs and mRNAs. Allelic variants and splice variants of these sequences can be cloned by probing cDNA or genomic libraries from different individuals or tissues according to standard procedures known in the art. For example, the short-form and long-form soluble zcytor17 receptors described above, and in SEQ ID NO: 112 and SEQ ID NO: 113 or SEQ ID NO: 114 and SEQ ID NO: 115 can be considered allelic or splice variants of zcytor17.

[0119] The present invention also provides isolated zcytor17 polypeptides that are substantially similar to the polypeptides of SEQ ID NO: 111, SEQ ID NO: 109 or SEQ ID NO: 5 and their orthologs, e.g., SEQ ID NO: 117 and SEQ ID NO: 119. The term “substantially similar” is used herein to denote polypeptides having at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or greater than 99% sequence identity to the sequences shown in SEQ ID NO: 111, SEQ ID NO: 109 or SEQ ID NO: 5 or their orthologs, e.g., SEQ ID NO: 117 and SEQ ID NO: 119. Such polypeptides will more preferably be at least 90% identical, and most preferably 95% or more identical to SEQ ID NO: 111, SEQ ID NO: 109 and SEQ ID NO: 5 or its orthologs.) Percent sequence identity is determined by conventional methods. See, for example, Altschul et al., Bull. Math. Bio. 48: 603-616, 1986 and Henikoff and Henikoff, Proc. Natl. Acad. Sci. USA 89:10915-10919, 1992. Briefly, two amino acid sequences are aligned to optimize the alignment scores using a gap opening penalty of 10, a gap extension penalty of 1, and the “blosum 62”scoring matrix of Henikoff and Henikoff (ibid.) as shown in Table 4 (amino acids are indicated by the standard one-letter codes). The percent identity is then calculated as: $\frac{{Total}\quad {number}\quad {of}\quad {identical}\quad {matches}}{\begin{matrix} \left\lbrack {{length}\quad {of}\quad {the}\quad {longer}\quad {sequences}\quad {plus}\quad {the}\quad {number}\quad {gaps}}\quad \right. \\ \left. {{introduced}\quad {into}\quad {the}\quad {longer}\quad {sequence}\quad {in}\quad {order}\quad {to}\quad {align}\quad {the}\quad {two}\quad {sequences}} \right\rbrack \end{matrix}} \times 100$

[0120] Sequence identity of polynucleotide molecules is determined by similar methods using a ratio as disclosed above.

[0121] Those skilled in the art appreciate that there are many established algorithms available to align two amino acid sequences. The “FASTA” similarity search algorithm of Pearson and Lipman is a suitable protein alignment method for examining the level of identity shared by an amino acid sequence disclosed herein and the amino acid sequence of a putative variant zcytor17. The FASTA algorithm is described by Pearson and Lipman, Proc. Nat'l Acad. Sci. USA 85:2444 (1988), and by Pearson, Meth. Enzymol. 183:63 (1990).

[0122] Briefly, FASTA first characterizes sequence similarity by identifying regions shared by the query sequence (e.g., SEQ ID NO: 111, SEQ ID NO: 109, SEQ ID NO: 5, SEQ ID NO: 117 and SEQ ID NO: 119) and a test sequence that have either the highest density of identities (if the ktup variable is 1) or pairs of identities (if ktup=2), without considering conservative amino acid substitutions, insertions, or deletions. The ten regions with the highest density of identities are then rescored by comparing the similarity of all paired amino acids using an amino acid substitution matrix, and the ends of the regions are “trimmed” to include only those residues that contribute to the highest score. If there are several regions with scores greater than the “cutoff” value (calculated by a predetermined formula based upon the length of the sequence and the ktup value), then the trimmed initial regions are examined to determine whether the regions can be joined to form an approximate alignment with gaps. Finally, the highest scoring regions of the two amino acid sequences are aligned using a modification of the Needleman-Wunsch-Sellers algorithm (Needleman and Wunsch, J. Mol. Biol. 48:444 (1970); Sellers, SIAM J. Appl. Math. 26:787 (1974)), which allows for amino acid insertions and deletions. Preferred parameters for FASTA analysis are: ktup=1, gap opening penalty=10, gap extension penalty=1, and substitution matrix=BLOSUM62, with other parameters set as default. These parameters can be introduced into a FASTA program by modifying the scoring matrix file (“SMATRIX”), as explained in Appendix 2 of Pearson, Meth. Enzymol. 183:63 (1990).

[0123] FASTA can also be used to determine the sequence identity of nucleic acid molecules using a ratio as disclosed above. For nucleotide sequence comparisons, the ktup value can range between one to six, preferably from three to six, most preferably three, with other FASTA program parameters set as default.

[0124] The BLOSUM62 table (Table 4) is an amino acid substitution matrix derived from about 2,000 local multiple alignments of protein sequence segments, representing highly conserved regions of more than 500 groups of related proteins (Henikoff and Henikoff, Proc. Nat'l Acad. Sci. USA 89:10915 (1992)). Accordingly, the BLOSUM62 substitution frequencies can be used to define conservative amino acid substitutions that may be introduced into the amino acid sequences of the present invention. Although it is possible to design amino acid substitutions based solely upon chemical properties (as discussed below), the language “conservative amino acid substitution” preferably refers to a substitution represented by a BLOSUM62 value of greater than −1. For example, an amino acid substitution is conservative if the substitution is characterized by a BLOSUM62 value of 0, 1, 2, or 3. According to this system, preferred conservative amino acid substitutions are characterized by a BLOSUM62 value of at least 1 (e.g., 1, 2 or 3), while more preferred conservative amino acid substitutions are characterized by a BLOSUM62 value of at least 2 (e.g., 2 or 3).

[0125] Variant zcytor17 polypeptides or substantially homologous zcytor17 polypeptides are characterized as having one or more amino acid substitutions, deletions or additions. These changes are preferably of a minor nature, that is conservative amino acid substitutions (see Table 5) and other substitutions that do not significantly affect the folding or activity of the polypeptide; small deletions, typically of one to about 30 amino acids; and small amino- or carboxyl-terminal extensions, such as an amino-terminal methionine residue, a small linker peptide of up to about 20-25 residues, or an affinity tag. The present invention thus includes polypeptides that comprise a sequence that is at least 80%, preferably at least 90%, and more preferably 95% or more identical to the corresponding region of SEQ ID NO: 111, SEQ ID NO: 109, SEQ ID NO: 5, SEQ ID NO: 117 or SEQ ID NO: 119 excluding the tags, extension, linker sequences and the like. Polypeptides comprising affinity tags can further comprise a proteolytic cleavage site between the zcytor17 polypeptide and the affinity tag. Suitable sites include thrombin cleavage sites and factor Xa cleavage sites.

The polynucleotide may encode a polypeptide that is included in a soluble multimeric cytokine receptor and that may also include an affinity tag as described herein. The polypeptide may comprise, for example, amino acid residue 20 to 227 to SEQ ID NO: 111, amino acid residue 20 to 519 to SEQ ID NO: 111, amino acid residue 20 to 543 to SEQ ID NO: 111, and/or combinations thereof. In addition, the at least a portion of at least one class I cytokine receptor may comprise, for example, amino acid residue 28 to 739 to SEQ ID NO: 7, amino acid residue 28 to 429 to SEQ ID NO: 7, amino acid residue 35 to 137 to SEQ ID NO: 7, amino acid residue 240 to 342 to SEQ ID NO: 7, amino acid residue 348 to 429 to SEQ ID NO: 7, and/or combinations thereof. The soluble multimeric cytokine receptor may be a heterodimer, trimer, tetramer, pentamer, or the like. The at least a portion of SEQ ID NO: 2 may include, for instance amino acid residues of SEQ ID NO: 2 selected from the group of 38 to 152, 27 to 164, 24 to 164, 1 to 164, 38 to 52, 83 to 98, 104 to 117, 137 to 152, and combinations thereof. Optionally, the multimeric cytokine receptor may antagonize an activity of SEQ ID NO: 2 as described herein.

[0131] The present invention further provides a variety of other polypeptide fusions and related multimeric proteins comprising one or more polypeptide fusions. For example, a zcytor17 polypeptide can be prepared as a fusion to a dimerizing protein as disclosed in U.S. Pat. Nos. 5,155,027 and 5,567,584. Preferred dimerizing proteins in this regard include immunoglobulin constant region domains. Immunoglobulin-zcytor17 polypeptide fusions can be expressed in genetically engineered cells to produce a variety of multimeric zcytor17 analogs. Auxiliary domains can be fused to zcytor17 polypeptides to target them to specific cells, tissues, or macromolecules (e.g., collagen). A zcytor17 polypeptide can be fused to two or more moieties, such as an affinity tag for purification and a targeting domain. Polypeptide fusions can also comprise one or more cleavage sites, particularly between domains. See, Tuan et al., Connective Tissue Research 34:1-9, 1996. For example, one or more domains from zcytor17 soluble receptor can be joined to a soluble cytokine receptor, such as OSMRbeta and/or WSX-1, which may enhance their biological properties or efficiency of production. Additionally, the soluble multimeric cytokine receptor may further include an affinity tag. An affinity tag can be, for example, a tag selected from the group of polyhistidine, protein A, glutathione S transferase, Glu-Glu, substance P, Flag™ peptide, streptavidin binding peptide, and an immunoglobulin F_(c) polypeptide.

[0132] The proteins of the present invention can also comprise non-naturally occurring amino acid residues. Non-naturally occurring amino acids include, without limitation, trans-3-methylproline, 2,4-methanoproline, cis-4-hydroxyproline, trans-4-hydroxyproline, N-methylglycine, allo-threonine, methylthreonine, hydroxyethylcysteine, hydroxyethylhomocysteine, nitroglutamine, homoglutamine, pipecolic acid, thiazolidine carboxylic acid, dehydroproline, 3- and 4-methylproline, 3,3-dimethylproline, tert-leucine, norvaline, 2-azaphenylalanine, 3-azaphenylalanine, 4-azaphenylalanine, and 4-fluorophenylalanine. Several methods are known in the art for incorporating non-naturally occurring amino acid residues into proteins. For example, an in vitro, system can be employed wherein nonsense mutations are suppressed using chemically aminoacylated suppressor tRNAs. Methods for synthesizing amino acids and aminoacylating tRNA are known in the art. Transcription and translation of plasmids containing nonsense mutations is carried out in a cell-free system comprising an E. coli S30 extract and commercially available enzymes and other reagents. Proteins are purified by chromatography. See, for example, Robertson et al., J. Am. Chem. Soc. 113:2722, 1991; Ellman et al., Methods Enzymol. 202:301, 1991; Chung et al., Science 259:806-9, 1993; and Chung et al., Proc. Natl. Acad. Sci. USA 90:10145-9, 1993). In a second method, translation is carried out in Xenopus oocytes by microinjection of mutated mRNA and chemically aminoacylated suppressor tRNAs (Turcatti et al., J. Biol. Chem. 271:19991-8, 1996). Within a third method, E. coli cells are cultured in the absence of a natural amino acid that is to be replaced (e.g., phenylalanine) and in the presence of the desired non-naturally occurring amino acid(s) (e.g., 2-azaphenylalanine, 3-azaphenylalanine, 4-azaphenylalanine, or 4-fluorophenylalanine). The non-naturally occurring amino acid is incorporated into the protein in place of its natural counterpart. See, Koide et al., Biochem. 33:7470-7476, 1994. Naturally occurring amino acid residues can be converted to non-naturally occurring species by in vitro chemical modification. Chemical modification can be combined with site-directed mutagenesis to further expand the range of substitutions (Wynn and Richards, Protein Sci. 2:395-403, 1993).

[0133] A limited number of non-conservative amino acids, amino acids that are not encoded by the genetic code, non-naturally occurring amino acids, and unnatural amino acids may be substituted for zcytor17 amino acid residues.

[0134] Essential amino acids in the polypeptides of the present invention can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, Science 244: 1081-5, 1989; Bass et al., Proc. Natl. Acad. Sci. USA 88:4498-502, 1991). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant molecules are tested for biological activity (e.g. ligand binding and signal transduction) as disclosed below to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., J. Biol. Chem. 271:4699-4708, 1996. Sites of ligand-receptor, protein-protein or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction or photoaffinity labeling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., Science 255:306-312, 1992; Smith et al., J. Mol. Biol. 224:899-904, 1992; Wlodaver et al., FEBS Lett. 309:59-64, 1992. The identities of essential amino acids can also be inferred from analysis of homologies with related receptors.

[0135] Determination of amino acid residues that are within regions or domains that are critical to maintaining structural integrity can be determined. Within these regions one can determine specific residues that will be more or less tolerant of change and maintain the overall tertiary structure of the molecule. Methods for analyzing sequence structure include, but are not limited to, alignment of multiple sequences with high amino acid or nucleotide identity and computer analysis using available software (e.g., the Insight II® viewer and homology modeling tools; MSI, San Diego, Calif.), secondary structure propensities, binary patterns, complementary packing and buried polar interactions (Barton, Current Opin. Struct. Biol. 5:372-376, 1995 and Cordes et al., Current Opin. Struct. Biol. 6:3-10, 1996). In general, when designing modifications to molecules or identifying specific fragments determination of structure will be accompanied by evaluating activity of modified molecules.

[0136] Amino acid sequence changes are made in zcytor17 polypeptides so as to minimize disruption of higher order structure essential to biological activity. For example, when the zcytor17 polypeptide comprises one or more helices, changes in amino acid residues will be made so as not to disrupt the helix geometry and other components of the molecule where changes in conformation abate some critical function, for example, binding of the molecule to its binding partners. The effects of amino acid sequence changes can be predicted by, for example, computer modeling as disclosed above or determined by analysis of crystal structure (see, e.g., Lapthorn et al., Nat. Struct. Biol. 2:266-268, 1995). Other techniques that are well known in the art compare folding of a variant protein to a standard molecule (e.g., the native protein). For example, comparison of the cysteine pattern in a variant and standard molecules can be made. Mass spectrometry and chemical modification using reduction and alkylation provide methods for determining cysteine residues which are associated with disulfide bonds or are free of such associations (Bean et al., Anal. Biochem. 201:216-226, 1992; Gray, Protein Sci. 2:1732-1748, 1993; and Patterson et al., Anal. Chem. 66:3727-3732, 1994). It is generally believed that if a modified molecule does not have the same disulfide bonding pattern as the standard molecule folding would be affected. Another well known and accepted method for measuring folding is circular dichrosism (CD). Measuring and comparing the CD spectra generated by a modified molecule and standard molecule is routine (Johnson, Proteins 7:205-214, 1990). Crystallography is another well known method for analyzing folding and structure. Nuclear magnetic resonance (NMR), digestive peptide mapping and epitope mapping are also known methods for analyzing folding and structural similarities between proteins and polypeptides (Schaanan et al., Science 257:961-964, 1992).

[0137] A Hopp/Woods hydrophilicity profile of the zcytor17 protein sequence as shown in SEQ ID NO: 2, SEQ ID NO: 46, SEQ ID NO: 54, SEQ ID NO: 57 and SEQ ID NO: 93 can be generated (Hopp et al., Proc. Natl. Acad. Sci. 78:3824-3828, 1981; Hopp, J. Immun. Meth. 88:1-18, 1986 and Triquier et al., Protein Engineering 11:153-169, 1998). See, FIG. 1. The profile is based on a sliding six-residue window. Buried G. S, and T residues and exposed H, Y, and W residues were ignored. For example, in zcytor17, hydrophilic regions include amino acid residues 43 through 48 of SEQ ID NO: 2 and SEQ ID NO: 46 (residues 56 through 61 of SEQ ID NO: 54), amino acid residues 157 through 162 of SEQ ID NO: 2 and SEQ ID NO: 46 (residues 170 through 175 of SEQ ID NO: 54), amino acid residues 158 through 163 of SEQ ID NO: 2 and SEQ ID NO: 46 (residues 171 through 176 of SEQ ID NO: 54), amino acid residues 221 through 226 of SEQ ID NO: 2 and SEQ ID NO: 46 (residues 234 through 239 of SEQ ID NO: 54), and amino acid residues 426 through 431 of SEQ ID NO: 2 and SEQ ID NO: 46 (residues 439 through 444 of SEQ ID NO: 54).

[0138] Those skilled in the art will recognize that hydrophilicity or hydrophobicity will be taken into account when designing modifications in the amino acid sequence of a zcytor17 polypeptide, so as not to disrupt the overall structural and biological profile. Of particular interest for replacement are hydrophobic residues selected from the group consisting of Val, Leu and lie or the group consisting of Met, Gly, Ser, Ala, Tyr and Trp. For example, residues tolerant of substitution could include such residues as shown in SEQ ID NO: 2, SEQ ID NO: 46, SEQ ID NO: 54, SEQ ID NO: 57 and SEQ ID NO: 93. However, Cysteine residues would be relatively intolerant of substitution.

[0139] The identities of essential amino acids can also be inferred from analysis of sequence similarity between class I cytokine receptor family members with zcytor17. Using methods such as “FASTA” analysis described previously, regions of high similarity are identified within a family of proteins and used to analyze amino acid sequence for conserved regions. An alternative approach to identifying a variant zcytor17 polynucleotide on the basis of structure is to determine whether a nucleic acid molecule encoding a potential variant zcytor17 polynucleotide can hybridize to a nucleic acid molecule having the nucleotide sequence of SEQ ID NO: 1, SEQ ID NO: 45 or SEQ ID NO: 53, as discussed above.

[0140] Other methods of identifying essential amino acids in the polypeptides of the present invention are procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, Science 244:1081 (1989), Bass et al., Proc. Natl Acad. Sci. USA 88:4498 (1991), Coombs and Corey, “Site-Directed Mutagenesis and Protein Engineering,” in Proteins: Analysis and Design, Angeletti (ed.), pages 259-311 (Academic Press, Inc. 1998)). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant molecules are tested for biological activity as disclosed below to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., J. Biol. Chem. 271:4699 (1996).

[0141] The present invention also includes a multimeric cytokine receptor which includes functional fragments of zcytor17 polypeptides and nucleic acid molecules encoding such functional fragments. A “functional” zcytor17 or fragment thereof defined herein is characterized by its ability to mediate proliferative or differentiating activity, by its ability to induce or inhibit specialized cell functions, or by its ability to bind specifically to an anti-zcytor17 antibody or zcytor17 ligand (either soluble or immobilized). Moreover, functional fragments also include the signal peptide, intracellular signaling domain, and the like. As-previously described herein, zcytor17 is characterized by a class I cytokine receptor structure. Thus, the present invention further provides fusion proteins encompassing: (a) polypeptide molecules comprising an extracellular domain, cytokine-binding domain, or intracellular domain described herein; and (b) functional fragments comprising one or more of these domains. The other polypeptide portion of the fusion protein may comprise at least a portion of one or more of another class I cytokine receptor, for example, gp130, LIF, IL-12, WSX-1, IL-2 receptor β-subunit and the β-common receptor (i.e., IL3, IL-5, and GM-CSF receptor β-subunits), or by a non-native and/or an unrelated secretory signal peptide that facilitates secretion of the fusion protein.

[0142] Routine deletion analyses of nucleic acid molecules can be performed to obtain functional fragments of a nucleic acid molecule that encodes a zcytor17 polypeptide. As an illustration, DNA molecules having the nucleotide sequence of SEQ ID NO: 1, SEQ ID NO: 45 or SEQ ID NO: 53 or fragments thereof, can be digested with Bal31 nuclease to obtain a series of nested deletions. These DNA fragments are then inserted into expression vectors in proper reading frame, and the expressed polypeptides are isolated and tested for zcytor17 activity, or for the ability to bind anti-zcytor17 antibodies or zcytor17 ligand. One alternative to exonuclease digestion is to use oligonucleotide-directed mutagenesis to introduce deletions or stop codons to specify production of a desired zcytor17 fragment. Alternatively, particular fragments of a zcytor17 polynucleotide can be synthesized using the polymerase chain reaction.

[0143] Standard methods for identifying functional domains are well-known to those of skill in the art. For example, studies on the truncation at either or both termini of interferons have been summarized by Horisberger and Di Marco, Pharmac. Ther. 66:507 (1995). Moreover, standard techniques for functional analysis of proteins are described by, for example, Treuter et al., Molec. Gen. Genet. 240:113 (1993); Content et al., “Expression and preliminary deletion analysis of the 42 kDa 2-5A synthetase induced by human interferon,” in Biological Interferon Systems, Proceedings of ISIR-TNO Meeting on Interferon Systems, Cantell (ed.), pages 65-72 (Nijhoff 1987); Herschman, “The EGF Receptor,” in Control of Animal Cell Proliferation 1, Boynton et al., (eds.) pages 169-199 (Academic Press 1985); Coumailleau et al., J. Biol. Chem. 270:29270 (1995); Fukunaga et al., J. Biol. Chem. 270:25291 (1995); Yamaguchi et al., Biochem. Pharnacol. 50:1295 (1995); and Meisel et al., Plant Molec. Biol. 30:1 (1996).

[0144] Multiple amino acid substitutions can be made and tested using known methods of mutagenesis and screening, such as those disclosed by Reidhaar-Olson and Sauer (Science 241:53-57, 1988) or Bowie and Sauer (Proc. Natl. Acad. Sci. USA 86:2152-2156, 1989). Briefly, these authors disclose methods for simultaneously randomizing two or more positions in a polypeptide, selecting for functional polypeptide, and then sequencing the mutagenized polypeptides to determine the spectrum of allowable substitutions at each position. Other methods that can be used include phage display (e.g., Lowman et al., Biochem. 30:10832-10837, 1991; Ladner et al., U.S. Pat. No. 5,223,409; Huse, WIPO Publication WO 92/062045) and region-directed mutagenesis (Derbyshire et al., Gene 46:145, 1986; Ner et al., DNA 7:127, 1988).

[0145] Variants of the disclosed zcytor17 DNA and polypeptide sequences can be generated through DNA shuffling as disclosed by Stemmer, Nature 370:389-91, 1994, Stemmer, Proc. Natl. Acad. Sci. USA 91:10747-51, 1994 and WEPO Publication WO 97/20078. Briefly, variant DNAs are generated by in vitro homologous recombination by random fragmentation of a parent DNA followed by reassembly using PCR, resulting in randomly introduced point mutations. This technique can be modified by using a family of parent DNAs, such as allelic variants or DNAs from different species, to introduce additional variability into the process. Selection or screening for the desired activity, followed by additional iterations of mutagenesis and assay provides for rapid “evolution” of sequences by selecting for desirable mutations while simultaneously selecting against detrimental changes.

[0146] Mutagenesis methods as disclosed herein can be combined with high-throughput, automated screening methods to detect activity of cloned, mutagenized zcytor17 receptor polypeptides in host cells. Preferred assays in this regard include cell proliferation assays and biosensor-based ligand-binding assays, which are described below. Mutagenized DNA molecules that encode active receptors or portions thereof (e.g., ligand-binding fragments, signaling domains, and the like) can be recovered from the host cells and rapidly sequenced using modern equipment. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide of interest, and can be applied to polypeptides of unknown structure.

[0147] The present invention also provides a novel multimeric cytokine receptor in which a segment comprising at least a portion of one or more of the domains of zcytor17, for instance, secretory, extracellular, transmembrane, and intracellular, is fused to another polypeptide, for example, an extracellular domain of a class I cytokine receptor, such as OSMRbeta and/or WSX-1. Fusion is preferably done by splicing at the DNA level to allow expression of chimeric molecules in recombinant production systems. The resultant molecules are then assayed for such properties as improved solubility, improved stability, prolonged clearance half-life, improved expression and secretion levels, and pharmacodynamics. Such a multimeric cytokine receptor may further comprise additional amino acid residues (e.g., a polypeptide linker) between the component proteins or polypeptides. A domain linker may comprise a sequence of amino acids from about 3 to about 20 amino acids long, from about 5 to 15 about amino acids long, from about 8 to about 12 amino acids long, and about 10 amino acids long. One function of a linker is to separate the active protein regions to promote their independent bioactivity and permit each region to assume its bioactive conformation independent of interference from its neighboring structure.

[0148] Using the methods discussed herein, one of ordinary skill in the art can identify and/or prepare a variety of polypeptide fragments or variants of SEQ ID NO: 111, SEQ ID NO: 109, SEQ ID NO: 5, SEQ ID NO: 117 and SEQ ID NO: 119 that retain the signal transduction or ligand binding activity. For example, one can make a zcytor17 “soluble receptor” by preparing a variety of polypeptides that are substantially homologous to the cytokine-binding domain (residues 20 (Ala) to 227 (Pro) of SEQ ID NO: 111 and SEQ ID NO: 109; residues 33 (Ala) to 240 (Pro) of SEQ ID NO: 5), the extracellular domain (residues 20 (Ala) to 519 (Glu) of SEQ ID NO: 111 and SEQ ID NO: 109; residues 33 (Ala) to 532 (Glu) of SEQ ID NO: 5), or allelic variants or species orthologs thereof (e.g., see SEQ. ID NO: 117 and SEQ ID NO: 119 and functional fragments thereof as described herein)) and retain ligand-binding activity of the wild-type zcytor17 protein. Moreover, variant zcytor17 soluble receptors such as those shown in SEQ ID NO: 113 and SEQ ID NO: 115 can be isolated. Such polypeptides may include additional amino acids from, for example, part or all of the transmembrane and intracellular domains. Such polypeptides may also include additional polypeptide segments as generally disclosed herein such as labels, affinity tags, and the like.

[0149] For any zcytor17 polypeptide, including variants, soluble receptors, and fusion polypeptides or proteins, one of ordinary skill in the art can readily generate a fully degenerate polynucleotide sequence encoding that variant using the information set forth in Tables 1 and 2 above.

[0150] The zcytor17 multimeric cytokine receptors of the present invention, including full-length polypeptides, biologically active fragments, and fusion polypeptides, can be produced in genetically engineered host cells according to conventional techniques. Suitable host cells are those cell types that can be transformed or transfected with exogenous DNA and grown in culture, and include bacteria, fungal cells, and cultured higher eukaryotic cells. Eukaryotic cells, particularly cultured cells of multicellular organisms, are preferred. Techniques for manipulating cloned DNA molecules and introducing exogenous DNA into a variety of host cells are disclosed by Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1989, and Ausubel et al., eds., Current Protocols in Molecular Biology, John Wiley and Sons, Inc., NY, 1987.

[0151] The present invention also provides an expression vector comprising an isolated and purified DNA molecule including the following operably linked elements: a first transcription promoter, a first DNA segment encoding a polypeptide having at least 90 percent sequence identity with SEQ ID NO: 111, and a first transcription terminator; and a second transcription promoter, a second DNA segment encoding at least a portion of a class I cytokine receptor, and a second transcription terminator; wherein the polypeptide and the class I cytokine receptor form a multimeric cytokine receptor; and wherein the multimeric cytokine receptor binds to at least a portion of SEQ ID NO: 2. The DNA molecule may further comprise a secretory signal sequence operably linked to the first and second DNA segments. The multimeric cytokine receptor may be soluble and/or may further comprise an affinity tag as described herein. In addition, the multimeric cytokine receptor may antagonize an activity of SEQ ID NO: 2 as described herein. The at least at portion of a class I cytokine receptor may comprise portions of SEQ ID NO: 7 and/or SEQ ID NO: 9, such as, for instance, amino acid residue 28 to amino acid residue 429 of SEQ ID NO: 7, amino acid residue 35 to amino acid residue 137 of SEQ ID NO: 7, amino acid residue 240 to amino acid residue 342 of SEQ ID NO: 7, amino acid residue 348 to amino acid residue 429 of SEQ ID NO: 7, amino acid residue 28 to amino acid residue 739 of SEQ ID NO: 7, amino acid residue 28 to amino acid residue 761 of SEQ ID NO: 7, amino acid residue 762 to amino acid residue 979 of SEQ ID NO: 7, or combinations thereof. The present invention also provides a cultured cell containing the above-described expression vector.

[0152] In general, a DNA sequence, for example, encoding a zcytor17 polypeptide is operably linked to other genetic elements required for its expression, generally including a transcription promoter and terminator, within an expression vector. The vector will also commonly contain one or more selectable markers and one or more origins of replication, although those skilled in the art will recognize that within certain systems selectable markers may be provided on separate vectors, and replication of the exogenous DNA may be provided by integration into the host cell genome. Selection of promoters, terminators, selectable markers, vectors and other elements is a matter of routine design within the level of ordinary skill in the art. Many such elements are described in the literature and are available through commercial suppliers.

[0153] To direct, for example, a zcytor17 polypeptide into the secretory pathway of a host cell, a secretory signal sequence (also known as a leader sequence, prepro sequence or pre sequence) is provided in the expression vector. The secretory signal sequence may be that of zcytor17, or may be derived from another secreted protein (e.g., t-PA) or synthesized de novo. The secretory signal sequence is operably linked to the zcytor17 DNA sequence, i.e., the two sequences are joined in the correct reading frame and positioned to direct the newly synthesized polypeptide into the secretory pathway of the host cell. Secretory signal sequences are commonly positioned 5′ to the DNA sequence encoding the polypeptide of interest, although certain secretory signal sequences may be positioned elsewhere in the DNA sequence of interest (see, e.g., Welch et al., U.S. Pat. No. 5,037,743; Holland et al., U.S. Pat. No. 5,143,830).

[0154] Alternatively, the secretory signal sequence contained in the polypeptides of the present invention is used to direct other polypeptides into the secretory pathway. The present invention provides for such fusion polypeptides. A signal fusion polypeptide can be made wherein a secretory signal sequence derived from amino acid 1 (Met) to amino acid 19 (Ala) of SEQ ID NO: 111 and SEQ ID NO: 109, or wherein a secretory signal sequence derived from amino acid 1 (Met) to amino acid 32 (Ala) of SEQ ID NO: 5, or amino acid 1 (Met) to amino acid 45 (Ala) of SEQ ID NO: 117 or SEQ ID NO: 119), or amino acid 28 (Met) to residue 45 (Ala) of SEQ ID NO: 117 or SEQ ID NO: 119), is operably linked to another polypeptide using methods known in the art and disclosed herein. The secretory signal sequence contained in the fusion polypeptides of the present invention is preferably fused amino-terminally to an additional peptide to direct the additional peptide into the secretory pathway. Such constructs have numerous applications known in the art. For example, these novel secretory signal sequence fusion constructs can direct the secretion of an active component of a normally non-secreted protein. Such fusions may be used in vivo or in vitro to direct peptides through the secretory pathway.

[0155] The present invention also provides a cultured cell comprising a first expression vector comprising a DNA molecule containing the following operably linked elements: a transcription promoter, a DNA segment encoding a polypeptide having at least 90 percent sequence identity with SEQ ID NO: 111, and a transcription terminator; and a second expression vector comprising a transcription promoter, a DNA segment encoding at least a portion of a class I cytokine receptor, and a transcription terminator; wherein the polypeptide and the class I cytokine receptor form a multimeric cytokine receptor. The first and second expression vectors may further comprise a secretory signal sequence operably linked to the first and second DNA segments. The multimeric cytokine receptor may be soluble, may be a heterodimer, and/or may further comprise an affinity tag as described herein. In addition, the multimeric cytokine receptor may antagonize an activity of SEQ ID NO: 2 as described herein. The at least at portion of a class I cytokine receptor may comprise portions of SEQ ID NO: 7 and/or SEQ ID NO: 9, such as, for instance, amino acid residue 28 to amino acid residue 429 of SEQ ID NO: 7, amino acid residue 35 to amino acid residue 137 of SEQ ID NO: 7, amino acid residue 240 to amino acid residue 342 of SEQ ID NO: 7, amino acid residue 348 to amino acid residue 429 of SEQ ID NO: 7, amino acid residue 28 to amino acid residue 739 of SEQ ID NO: 7, amino acid residue 28 to amino acid residue 761 of SEQ ID NO: 7, amino acid residue 762 to amino acid residue 979 of SEQ ID NO: 7, or combinations thereof.

[0156] Cultured mammalian cells are suitable hosts within the present invention. Methods for introducing exogenous DNA into mammalian host cells include calcium phosphate-mediated transfection (Wigler et al., Cell 14:725, 1978; Corsaro and Pearson, Somatic Cell Genetics 7:603, 1981: Graham and Van der Eb, Virology 52:456, 1973), electroporation (Neumann et al., EMBO J. 1:841-845, 1982), DEAE-dextran mediated transfection (Ausubel et al., ibid.), and liposome-mediated transfection (Hawley-Nelson et al., Focus 15:73, 1993; Ciccarone et al., Focus 15:80, 1993, and viral vectors (Miller and Rosman, BioTechniques 7:980-90, 1989; Wang and Finer, Nature Med. 2:714-716, 1996). The production of recombinant polypeptides in cultured mammalian cells is disclosed, for example, by Levinson et al., U.S. Pat. No. 4,713,339; Hagen et al., U.S. Pat. No. 4,784,950; Palmiter et al., U.S. Pat. No. 4,579,821; and Ringold, U.S. Pat. No. 4,656,134. Suitable cultured mammalian cells include the COS-1 (ATCC No. CRL 1650), COS-7 (ATCC No. CRL 1651), BHK (ATCC No. CRL 1632), BHK 570 (ATCC No. CRL 10314), 293 (ATCC No. CRL 1573; Graham et al., J. Gen. Virol. 36:59-72, 1977) and Chinese hamster ovary (e.g. CHO-K1; ATCC No. CCL 61) cell lines. Additional suitable cell lines are known in the art and available from public depositories such as the American Type Culture Collection, Rockville, Md. In general, strong transcription promoters are preferred, such as promoters from SV-40 or cytomegalovirus. See, e.g., U.S. Pat. No. 4,956,288. Other suitable promoters include those from metallothionein genes (U.S. Pat. Nos. 4,579,821 and 4,601,978) and the adenovirus major late promoter.

[0157] Drug selection is generally used to select for cultured mammalian cells into which foreign DNA has been inserted. Such cells are commonly referred to as “transfectants”. Cells that have been cultured in the presence of the selective agent and are able to pass the gene of interest to their progeny are referred to as “stable transfectants.” A preferred selectable marker is a gene encoding resistance to the antibiotic neomycin. Selection is carried out in the presence of a neomycin-type drug, such as G-418 or the like. Selection systems can also be used to increase the expression level of the gene of interest, a process referred to as “amplification.” Amplification is carried out by culturing transfectants in the presence of a low level of the selective agent and then increasing the amount of selective agent to select for cells that produce high levels of the products of the introduced genes. A preferred amplifiable selectable marker is dihydrofolate reductase, which confers resistance to methotrexate. Other drug resistance genes (e.g., hygromycin resistance, multi-drug resistance, puromycin acetyltransferase) can also be used. Alternative markers that introduce an altered phenotype, such as green fluorescent protein, or cell surface proteins such as CD4, CD8, Class I MHC, placental alkaline phosphatase may be used to sort transfected cells from untransfected cells by such means as FACS sorting or magnetic bead separation technology.

[0158] Other higher eukaryotic cells can also be used as hosts, including plant cells, insect cells and avian cells. The use of Agrobacterium rhizogenes as a vector for expressing genes in plant cells has been reviewed by Sinkar et al., J. Biosci. (Bangalore) 11:47-58, 1987. Transformation of insect cells and production of foreign polypeptides therein is disclosed by Guarino et al., U.S. Pat. No. 5,162,222 and WIPO publication WO 94/06463. Insect cells can be infected with recombinant baculovirus, commonly derived from Autographa californica nuclear polyhedrosis virus (AcNPV). See, King, L. A. and Possee, R. D., The Baculovirus Expression System: A Laboratory Guide, London, Chapman & Hall; O'Reilly, D. R. et al., Baculovirus Expression Vectors: A Laboratory Manual, New York, Oxford University Press., 1994; and, Richardson, C. D., Ed., Baculovirus Expression Protocols. Methods in Molecular Biology, Totowa, N. J., Humana Press, 1995. A second method of making recombinant zcytor17 baculovirus utilizes a transposon-based system described by Luckow (Luckow, V. A, et al., J Virol 67:4566-79, 1993). This system, which utilizes transfer vectors, is sold in the Bac-to-Bac™ kit (Life Technologies, Rockville, Md.). This system utilizes a transfer vector, pFastBac1™ (Life Technologies) containing a Tn7 transposon to move the DNA encoding the zcytor17 polypeptide into a baculovirus genome maintained in E. coli as a large plasmid called a “bacmid.” See, Hill-Perkins, M. S. and Possee, R. D., J Gen Virol 71:971-6, 1990; Bonning, B. C. et al., J Gen Virol 75:1551-6, 1994; and, Chazenbalk, G. D., and Rapoport, B., J Biol Chem 270:1543-9, 1995. In addition, transfer vectors can include an in-frame fusion with DNA encoding an epitope tag at the C- or N-terminus of the expressed zcytor17 polypeptide, for example, a Glu-Glu epitope tag (Grussenmeyer, T. et al., Proc. Natl. Acad. Sci. 82:7952-4, 1985). Using a technique known in the art, a transfer vector containing zcytor17 is transformed into E. coli, and screened for bacmids which contain an interrupted lacZ gene indicative of recombinant baculovirus. The bacmid DNA containing the recombinant baculovirus genome is isolated, using common techniques,. and used to transfect Spodoptera frugiperda cells, e.g., Sf9 cells. Recombinant virus that expresses zcytor17 is subsequently produced. Recombinant viral stocks are made by methods commonly used in the art.

[0159] The recombinant virus is used to infect host cells, typically a cell line derived from the fall armyworm, Spodoptera frugiperda. See, in general, Glick and Pasternak, Molecular Biotechnology: Principles and Applications of Recombinant DNA,. ASM Press, Washington, D.C., 1994. Another suitable cell line is the High FiveO™ cell line (Invitrogen) derived from Trichoplusia ni. (U.S. Pat. No. 5,300,435). Commercially available serum-free media are used to grow and maintain the cells. Suitable media are Sf900 II™ (Life Technologies) or ESF 921™ (Expression Systems) for the Sf9 cells; and Ex-cellO405™ (JRH Biosciences, Lenexa, Kans.) or Express FiveO™ (Life Technologies) for the T. ni cells. Procedures used are generally described in available laboratory manuals (King, L. A. and Possee, R. D., ibid.; O'Reilly, D. R. et al., ibid.; Richardson, C. D., ibid.). Subsequent purification of the zcytor17 polypeptide from the supernatant can be achieved using methods described herein.

[0160] Fungal cells, including yeast cells, can also be used within the present invention. Yeast species of particular interest in this regard include Saccharomyces cerevisiae, Pichia pastoris, and Pichia methanolica. Methods for transforming S. cerevisiae cells with exogenous DNA and producing recombinant polypeptides therefrom are disclosed by, for example, Kawasaki, U.S. Pat. No. 4,599,311; Kawasaki et al., U.S. Pat. No. 4,931,373; Brake, U.S. Pat. No. 4,870,008; Welch et al., U.S. Pat. No. 5,037,743; and Murray et al., U.S. Pat. No. 4,845,075. Transformed cells are selected by phenotype determined by the selectable marker, commonly drug resistance or the ability to grow in the absence of a particular nutrient (e.g., leucine). A preferred vector system for use in Saccharomyces cerevisiae is the POT1 vector system disclosed by Kawasaki et al. (U.S. Pat. No. 4,931,373), which allows transformed cells to be selected by growth in glucose-containing media. Suitable promoters and terminators for use in yeast include those from glycolytic enzyme genes (see, e.g., Kawasaki, U.S. Pat. No. 4,599,311; Kingsman et al., U.S. Pat. No. 4,615,974; and Bitter, U.S. Pat. No. 4,977,092) and alcohol dehydrogenase genes. See also U.S. Pat. Nos. 4,990,446; 5,063,154; 5,139,936 and 4,661,454. Transformation systems for other yeasts, including Hansenula polymorpha, Schizosaccharomyces pombe, Kluyveromyces lactis, Kluyveromyces fragilis, Ustilago maydis, Pichia pastoris, Pichia methanolica, Pichia guillernondii and Candida maltosa are known in the art. See, for example, Gleeson et al., J. Gen. Microbiol. 132:3459-3465, 1986 and Cregg, U.S. Pat. No. 4,882,279. Aspergillus cells may be utilized according to the methods of McKnight et al., U.S. Pat. No. 4,935,349. Methods for transforming Acremonium chrysogenum are disclosed by Sumino et al., U.S. Pat. No. 5,162,228. Methods for transforming Neurospora are disclosed by Lambowitz, U.S. Pat. No. 4,486,533.

[0161] The use of Pichia methanolica as host for the production of recombinant proteins is disclosed in WIPO Publications WO 97/17450, WO 97/17451, WO 98/02536, and WO 98/02565. DNA molecules for use in transforming P. methanolica will commonly be prepared as double-stranded, circular plasmids, which are preferably linearized prior to transformation. For polypeptide production in P. methanolica, it is preferred that the promoter and terminator in the plasmid be that of a P. methanolica gene, such as a P. methanolica alcohol utilization gene (AUG1 or AUG2). Other useful promoters include those of the dihydroxyacetone synthase (DHAS), formate dehydrogenase (FMD), and catalase (CAT) genes. To facilitate integration of the DNA into the host chromosome, it is preferred to have the entire expression segment of the plasmid flanked at both ends by host DNA sequences. A preferred selectable marker for use in Pichia methanolica is a P. methanolica ADE2 gene, which encodes phosphoribosyl-5-aminoimidazole carboxylase (AIRC; EC 4.1.1.21), which allows ade2 host cells to grow in the absence of adenine. For large-scale, industrial processes where it is desirable to minimize the use of methanol, it is preferred to use host cells in which both methanol utilization genes (AUG1 and AUG2) are deleted. For production of secreted proteins, host cells deficient in vacuolar protease genes (PEP4 and PRB1) are preferred. Electroporation is used to facilitate the introduction of a plasmid containing DNA encoding a polypeptide of interest into P. methanolica cells. It is preferred to transform P. methanolica cells by electroporation using an exponentially decaying, pulsed electric field having a field strength of from 2.5 to 4.5 kV/cm, preferably about 3.75 kV/cm, and a time constant (t) of from I to 40 milliseconds, most preferably about 20 milliseconds.

[0162] Prokaryotic host cells, including strains of the bacteria Escherichia coli, Bacillus and other genera are also useful host cells within the present invention.

[0163] Techniques for transforming these hosts and expressing foreign DNA sequences cloned therein are well known in the art (see, e.g., Sambrook et al., ibid.). When expressing a zcytor17 polypeptide in bacteria such as E. coli, the polypeptide may be retained in the cytoplasm, typically as insoluble granules, or may be directed to the periplasmic space by a bacterial secretion sequence. In the former case, the cells are lysed, and the granules are recovered and denatured using, for example, guanidine isothiocyanate or urea. The denatured polypeptide can then be refolded and dimerized by diluting the denaturant, such as by dialysis against a solution of urea and a combination of reduced and oxidized glutathione, followed by dialysis against a buffered saline solution. In the latter case, the polypeptide can be recovered from the periplasmic space in a soluble and functional form by disrupting the cells (by, for example, sonication or osmotic shock) to release the contents of the periplasmic space and recovering the protein, thereby obviating the need for denaturation and refolding.

[0164] Transformed or transfected host cells are cultured according to conventional procedures in a culture medium containing nutrients and other components required for the growth of the chosen host cells. A variety of suitable media, including defined media and complex media, are known in the art and generally include a carbon source, a nitrogen source, essential amino acids, vitamins and minerals. Media may also contain such components as growth factors or serum, as required. The growth medium will generally select for cells containing the exogenously added DNA by, for example, drug selection or deficiency in an essential nutrient which is complemented by the selectable marker carried on the expression vector or co-transfected into the host cell. P. methanolica cells are cultured in a medium comprising adequate sources of carbon, nitrogen and trace nutrients at a temperature of about 25° C. to 35° C. Liquid cultures are provided with sufficient aeration by conventional means, such as shaking of small flasks or sparging of fermentors. A preferred culture medium for P. methanolica is YEPD (2% D-glucose, 2% Bacto™ Peptone (Difco Laboratories, Detroit, Mich.), 1% Bacto™ yeast extract (Difco Laboratories), 0.004% adenine and 0.006% L-leucine).

[0165] Within one aspect of the present invention, a zcytor17 multimeric cytokine receptor (including transmembrane and intracellular domains) is produced by a cultured cell, and the cell is used to screen for ligands for the receptor, including the natural ligand (SEQ ID NO: 2), as well as agonists and antagonists of the natural ligand. To summarize this approach, a cDNA or gene encoding the receptor is combined with other genetic elements required for its expression (e.g., a transcription promoter), and the resulting expression vector is inserted into a host cell. Cells that express the DNA and produce functional receptor are selected and used within a variety of screening systems.

[0166] Mammalian cells suitable for use in expressing the novel receptors of the present invention and transducing a receptor-mediated signal include cells that express a β-subunit, such as gp130, and cells that co-express gp130 and LIF receptor (Gearing et al., EMBO J. 10:2839-2848, 1991; Gearing et al., U.S. Pat. No. 5,284,755). In this regard it is generally preferred to employ a cell that is responsive to other cytokines that bind to receptors in the same subfamily, such as IL-6 or LIF, because such cells will contain the requisite signal transduction pathway(s). Preferred cells of this type include BaF3 cells (Palacios and Steinmetz, Cell 41: 727-734, 1985; Mathey-Prevot et al., Mol. Cell. Biol. 6: 4133-4135, 1986), the human TF-1 cell line (ATCC number CRL-2003) and the DA-1 cell line (Branch et al., Blood 69:1782, 1987; Broudy et al., Blood 75:1622-1626, 1990). In the alternative, suitable host cells can be engineered to produce a β-subunit or other cellular component needed for the desired cellular response. For example, the murine cell line BaF3 (Palacios and Steinmetz, Cell 41:727-734, 1985; Mathey-Prevot et al., Mol. Cell. Biol. 6: 4133-4135, 1986), a baby hamster kidney (BHK) cell line, or the CTLL-2 cell line (ATCC TIB-214) can be transfected to express the mouse gp130 subunit, or mouse gp130 and LIF receptor, in addition to zcytor17. It is generally preferred to use a host cell and receptor(s) from the same species, however this approach allows cell lines to be engineered to express multiple receptor subunits from any species, thereby overcoming potential limitations arising from species specificity. In the alternative, species homologs of the human receptor cDNA can be cloned and used within cell lines from the same species, such as a mouse cDNA in the BaF3 cell line. Cell lines that are dependent upon one hematopoietic growth factor, such as IL-3, can thus be engineered to become dependent upon a zcytor17 ligand or anti-zcytor17 antibody.

[0167] Cells expressing functional zcytor17 are used within screening assays. A variety of suitable assays are known in the art. These assays are based on the detection of a biological response in the target cell. One such assay is a cell proliferation assay. Cells are cultured in the presence or absence of a test compound, and cell proliferation is detected by, for example, measuring incorporation of tritiated thymidine or by calorimetric assay based on the reduction or metabolic breakdown of Alymar Blue™ (AccuMed, Chicago, Ill.) or 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) (eMosman, J. Immunol. Meth. 65:55-63, 1983). An alternative assay format uses cells that are further engineered to express a reporter gene. The reporter gene is linked to a promoter element that is responsive to the receptor-linked pathway, and the assay detects activation of transcription of the reporter gene. A preferred promoter element in this regard is a serum response element, STAT or SRE (see, for example, Shaw et al., Cell 56:563-572, 1989). A preferred such reporter gene is a luciferase gene (de Wet et al., Mol. Cell. Biol. 7:725, 1987). Expression of the luciferase gene is detected by luminescence using methods known in the art (e.g., Baumgartner et al., J. Biol. Chem. 269:19094-29101, 1994; Schenborn and Goiffin, Promega Notes 41:11, 1993). Luciferase assay kits are commercially available from, for example, Promega Corp., Madison, Wis. Target cell lines of this type can be used to screen libraries of chemicals, cell-conditioned culture media, fungal broths, soil samples, water samples, and the like. For example, a bank of cell- or tissue-conditioned media samples can be assayed on a target cell to identify cells that produce ligand. Positive cells are then used to produce a cDNA library in a mammalian cell expression vector, which is divided into pools, transfected into host cells, and expressed. Media samples from the transfected cells are then assayed, with subsequent division of pools, retransfection, subculturing, and re-assay of positive cells to isolate a clonal cell line expressing the ligand. Media samples conditioned by kidney, liver, spleen, thymus, other lymphoid tissues, or T-cells are preferred sources of ligand for use in screening procedures.

[0168] The present invention also provides a method of producing a multimeric cytokine receptor. The method includes culturing a cell as described herein, and isolating the multimeric cytokine receptor produced by the cell.

[0169] The present invention also provides a method for detecting a multiple cytokine receptor ligand in a test sample. The method includes contacting the test sample with a multimeric cytokine receptor comprising a polypeptide comprising amino acid residue 20 to amino acid residue 227 of SEQ ID NO: 1I1 or SEQ ID NO: 109 (amino acid residue 33 to amino acid residue 240 of SEQ ID NO: 5), and at least a portion of at least one class I cytokine receptor; and detecting the binding of the multimer cytokine receptor to the ligand in the test sample. The at least a portion of at least one class I cytokine receptor can include, for example, a portion of SEQ ID NO: 9 and/or a portion of SEQ ID NO: 7, such as, for instance, amino acid residue 28 to amino acid residue 429 of SEQ ID NO: 7, amino acid residue 35 to amino acid residue 137 of SEQ ID NO: 7, amino acid residue 240 to amino acid residue 342 of SEQ ID NO: 7; amino acid residue 348 to amino acid residue 429 of SEQ ID NO: 7, amino acid residue 28 to amino acid residue 739 of SEQ ID NO: 7, and/or combinations thereof.

[0170] A natural ligand for a zcytor17 multimeric cytokine receptor of the present invention can also be identified by mutagenizing a cytokine-dependent cell line expressing zcytor17 and culturing it under conditions that select for autocrine growth. See WIPO publication WO 95/21930. Within a typical procedure, cells expressing zcytor17 are mutagenized, such as with EMS. The cells are then allowed to recover in the presence of the required cytokine, then transferred to a culture medium lacking the cytokine. Surviving cells are screened for the production of a ligand for zcytor17 multimeric cytokine receptor, such as by adding soluble receptor polypeptide comprising the zcytor17 cytokine-binding domain and at least a portion of a class I cytokine receptor, such as the cytokine-binding domain of OSMRbeta (SEQ ID NO: 7) and/or WSX-1 (SEQ ID NO: 9), as described herein to the culture medium to compete against the ligand or by assaying conditioned media on wild-type cells compared to transfected cells expressing the zcytor17 multimeric cytokine receptor. Preferred cell lines for use within this method include cells that are transfected to express gp130 or gp130 in combination with LIF receptor. Preferred such host cell lines include transfected CTLL-2 cells (Gillis and Smith, Nature 268:154-156, 1977) and transfected BaF3 cells.

[0171] Moreover, a secretion trap method employing zcytor17 soluble multimeric cytokine receptor can be used to isolate a zcytor17 ligand, such as SEQ ID NO: 2 (Aldrich, et al, Cell 87: 1161-1169, 1996). A cDNA expression library prepared from a known or suspected ligand source is transfected into COS-7 cells. The cDNA library vector generally has an SV40 origin for amplification in COS-7 cells, and a CMV promoter for high expression. The transfected COS-7 cells are grown in a monolayer and then fixed and permeabilized. Tagged or biotin-labeled zcytor17 soluble multimeric cytokine receptor, described herein, is then placed in contact with the cell layer and allowed to bind cells in the monolayer that express an anti-complementary molecule, i.e., a zcytor17 ligand. A cell expressing a ligand will thus be bound with receptor molecules. An anti-tag antibody (anti-Ig for Ig fusions, M2 or anti-FLAG for FLAG-tagged fusions, streptavidin, anti-Glu-Glu tag, and the like) which is conjugated with horseradish peroxidase (HRP) is used to visualize these cells to which the tagged or biotin-labeled zcytor17 soluble multimeric cytokine receptor has bound. The HRP catalyzes deposition of a tyramide reagent, for example, tyramide-FITC. A commercially-available kit can be used for this detection (for example, Renaissance TSA-Direct™ Kit; NEN Life Science Products, Boston, Mass.). Cells which express zcytor17 multimeric cytokine receptor ligand will be identified under fluorescence microscopy as green cells and picked for subsequent cloning of the ligand using procedures for plasmid rescue as outlined in Aldrich, et al, supra., followed by subsequent rounds of secretion trap assay, or conventional screening of cDNA library pools, until single clones are identified.

[0172] As a multimeric receptor complex, the activity of zcytor17 polypeptide can be measured by a silicon-based biosensor microphysiometer which measures the extracellular acidification rate or proton excretion associated with receptor binding and subsequent physiologic cellular responses. An exemplary device is the Cytosensor™ Microphysiometer manufactured by Molecular Devices, Sunnyvale, Calif. A variety of cellular responses, such as cell proliferation, ion transport, energy production, inflammatory response, regulatory and receptor activation, and the like, can be measured by this method. See, for example, McConnell, H. M. et al., Science 257:1906-1912, 1992; Pitchford, S. et al., Meth. Enzymol. 228:84-108, 1997; Arimilli, S. et al., J. Immunol. Meth. 212:49-59, 1998; Van Liefde, I. Et al., Eur. J. Pharmacol. 346:87-95, 1998. The microphysiometer can be used for assaying eukaryotic, prokaryotic, adherent or non-adherent cells. By measuring extracellular acidification changes in cell media over time, the microphysiometer directly measures cellular responses to various stimuli, including agonists, ligands, or antagonists of the zcytor17 polypeptide. Preferably, the microphysiometer is used to measure responses of a zcytor17-expressing eukaryotic cell, compared to a control eukaryotic cell that does not express zcytor17 polypeptide. Zcytor17-expressing eukaryotic cells comprise cells into which zcytor17 has been transfected or infected via adenovirus vector, and the like, as described herein, creating a cell that is responsive to zcytor17-modulating stimuli, or are cells naturally expressing zcytor17, such as zcytor17-expressing cells derived from lymphoid, spleen, thymus tissue or PBLs. Differences, measured by an increase or decrease in extracellular acidification, in the response of cells expressing zcytor17, relative to a control, are a direct measurement of zcytor17-modulated cellular responses. Moreover, such zcytor17-modulated responses can be assayed under a variety of stimuli. Also, using the microphysiometer, there is provided a method of identifying agonists and antagonists of zcytor17 multimeric cytokine receptor, comprising providing cells expressing a zcytor17 multimeric cytokine receptor, culturing a first portion of the cells in the absence of a test compound, culturing a second portion of the cells in the presence of a test compound, and detecting an increase or a decrease in a cellular response of the second portion of the cells as compared to the first portion of the cells. Antagonists and agonists, including the natural ligand for zcytor17 multimeric cytokine receptor, can be rapidly identified using this method.

[0173] A zcytor17 multimeric cytokine receptor can be expressed as a fusion with an immunoglobulin heavy chain constant region, typically an F_(c) fragment, which contains two constant region domains and lacks the variable region. Methods for preparing such fusions are disclosed in U.S. Pat. Nos. 5,155,027 and 5,567,584. Such fusions are typically secreted as multimeric molecules wherein the F_(c) portions are disulfide bonded to each other and two non-Ig polypeptides are arrayed in closed proximity to each other. Fusions of this type can be used for example, for dimerization, increasing stability and in vivo half-life, to affinity purify ligand, as in vitro assay tool or antagonist. For use in assays, the chimeras are bound to a support via the F_(c) region and used in an ELISA format.

[0174] Additional assays provided by the present invention include the use of hybrid receptor polypeptides. These hybrid polypeptides fall into two general classes. Within the first class, the intracellular domain of zcytor17, comprising approximately residues 544 (Lys) to 732 (Val) of SEQ ID NO: 111, residues 544 (Lys) to 649 (Ile) of SEQ ID NO: 109, or residues 557 (Lys) to 662 (Ile) of SEQ ID NO: 5, or residues 551 (Lys) to 662 (Cys) of SEQ ID NO: 117 is joined to the ligand-binding domain of a second receptor. It is preferred that the second receptor be a hematopoietic cytokine receptor, such as, for instance, mp1 receptor (Souyri et al., Cell 63:1137-1147, 1990). The hybrid receptor will further comprise a transmembrane domain, which may be derived from either receptor. A DNA construct encoding the hybrid receptor is then inserted into a host cell. Cells expressing the hybrid receptor are cultured in the presence of a ligand for the binding domain and assayed for a response. This system provides a means for analyzing signal transduction mediated by zcytor17 while using readily available ligands. This system can also be used to determine if particular cell lines are capable of responding to signals transduced by zcytor17. A second class of hybrid receptor polypeptides comprise the extracellular (ligand-binding) domain (approximately residues 20 (Ala) to 519 (Glu) of SEQ ID NO: 111 and SEQ ID NO: 109; approximately residues 33 (Ala) to 532 (Glu) of SEQ ID NO: 5) or cytokine-binding domain of zcytor17 (approximately residues 20 (Ala) to 227 (Pro) of SEQ ID NO: 111 and SEQ ID NO: 109; or approximately residues 33 (Ala) to 240 (Pro) of SEQ ID NO: 5; approximately residues 46 (Val) to 533 (Glu) of SEQ ID NO: 117; or approximately residues 46 (Val) to 533 (Trp) of SEQ ID NO: 119) with a cytoplasmic domain of a second receptor, preferably a cytokine receptor, and a transmembrane domain. The transmembrane domain may be derived from either receptor. Hybrid receptors of this second class are expressed in cells known to be capable of responding to signals transduced by the second receptor. Together, these two classes of hybrid receptors enable the use of a broad spectrum of cell types within receptor-based assay systems.

[0175] The expression of WSX-1 is strongest in thymus, spleen, PBL, and lymph node, as well as increased expression observed for activated T-cells. The tissue distribution for OSMRbeta is described as very broad. The tissue distribution of these three receptors suggests that a target for zcytor17lig is hematopoietic lineage cells, in particular T-cells, monocytes/macrophages and lymphoid progenitor cells and lymphoid cells. Other known four-helical-bundle cytokines that act on lymphoid cells include IL-2, IL-4, IL-7, and IL-15. For a review of four-helical-bundle cytokines, see, Nicola et al., Advances in Protein Chemistry 52:1-65, 1999 and Kelso, A., Immunol. Cell Biol. 76:300-317, 1998.

[0176] Conditioned media (CM) from CD3+ selected, PMA/Ionomycin-stimulated human peripheral blood cells supported the growth of BaF3 cells that expressed the zcytor17 receptor, OSMRbeta and WSX-1 receptor and were otherwise dependent on IL-3. Conditioned medias from cells that were not: 1) PMA/Ionomycin-stimulated; or were not: 2) CD3 selected (with or without PMA/Ionomycin stimulation) did not support the growth of Baf3 cells expressing zcytor17, OSMRbeta and WSX-1 (BaF3/zcytor1/WSX-1/OSMRbeta) receptor-expressing cells. Control experiments demonstrated that this proliferative activity was not attributable to other known growth factors, and that the ability of such conditioned media to stimulate proliferation of zcytor17/WSX-1/OSMRbeta receptor-expressing cells could be neutralized by a soluble form of the zcytor17 receptor.

[0177] Conditioned-media from CD3+ selected cells activated with PMA/Ionomycin also supported growth of BaF3 cells that expressed the zcytor17 receptor and OSMRbeta receptor (zcytor17/OSMRbeta), while BaF3 cells expressing only zcytor17 receptor and WSX-1 receptor (zcytor17AWSX-1), or containing only the OSMRbeta receptor, were not stimulated by this conditioned-media.

[0178] Proliferation of zcytor17/WSX-1/OSMRbeta receptor-expressing BaF3 cells exposed to CM from CD3+selected, PMA/Ionomycin-stimulated human peripheral blood cells were identified by visual inspection of the cultures and/or by proliferation assay. Many suitable proliferation assays are known in the art, and include assays for reduction of a dye such as AlamarBlue™ (AccuMed International, Inc. Westlake, Ohio), 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (Mosman, J. Immunol. Meth. 65: 55-63, 1983); 3,(4,5 dimethyl thiazol-2yl)-5-3-carboxymethoxyphenyl-2H-tetrazolium; 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)carbonyl]-2H-tetrazolium hydroxide; and cyanoditolyl-tetrazolium chloride (which are commercially available from Polysciences, Inc., Warrington, Pa.); mitogenesis assays, such as measurement of incorporation of ³H-thymidine; dye exclusion assays using, for example, naphthalene black or trypan blue; dye uptake using diacetyl fluorescein; and chromium release.

[0179] A cDNA library was prepared from CD3+ selected, PMA- and lonomycin-stimulated primary human peripheral blood cells. The CD3+ selected, PMA- and lonomycin-stimulated human peripheral blood cells cDNA library was divided into pools containing multiple cDNA molecules and was transfected into a host cell line, for example, BHK 570 cells (ATCC accession no. 10314). The transfected host cells were cultured in a medium that did not contain exogenous growth factors (e.g., 5% FBS) and conditioned medium was collected. The conditioned media were assayed for the ability to stimulate proliferation of BaF3 cells transfected with the zcytor17, WSX-1, and OSMRbeta receptors. cDNA pools producing conditioned medium that stimulated BaF3/zcytor17/WSX-1/OSMRbeta receptor cells were identified. This pooled plasmid cDNA was electroporated into E. coli. cDNA was isolated from single colonies and transfected individually into BHK 570 cells. Positive clones were identified by a positive result in the BaF3/zcytor17/WSX-1/OSMRbeta receptor proliferation assay, and the activity was confirmed by neutralization of proliferation using the soluble zcytor17 receptor.

[0180] In view of the tissue distribution observed for zcytor17 receptor agonists (including the natural zcytor17lig/ substrate/ cofactor/ etc.) and/or antagonists have enormous potential in both in vitro and in vivo applications. Compounds identified as zcytor17lig agonists are useful for expansion, proliferation, activation, differentiation, and/or induction or inhibition of specialized cell functions of cells involved in homeostasis of hematopoiesis and immune function. For example, zcytor17lig and agonist compounds are useful as components of defined cell culture media, and may be used alone or in combination with other cytokines and hormones to replace serum that is commonly used in cell culture. Agonists are thus useful in specifically promoting the growth and/or development of T-cells, B-cells, monocytes/macrophages, NK cells, cytotoxic lymphocytes, and other cells of the lymphoid and myeloid lineages in culture.

[0181] Antagonists are also useful as research reagents for characterizing sites of ligand-receptor interaction. Antagonists are useful to inhibit expansion, proliferation, activation, and/or differentiation of cells involved in regulating hematopoiesis. Inhibitors of zcytor17lig activity (zcytor17lig antagonists) include anti-zcytor17lig antibodies and soluble multimeric cytokine receptors, as well as other peptidic and non-peptidic agents (including ribozymes).

[0182] A zcytor17lig-binding protein, such as a multimeric cytokine receptor of the present invention, can also be used for purification of ligand. The multimeric cytokine receptor is immobilized on a solid support, such as beads of agarose, cross-linked agarose, glass, cellulosic resins, silica-based resins, polystyrene, cross-linked polyacrylamide, or like materials that are stable under the conditions of use. Methods for linking polypeptides to solid supports are known in the art, and include amine chemistry, cyanogen bromide activation, N-hydroxysuccinimide activation, epoxide activation, sulfhydryl activation, and hydrazide activation. The resulting medium will generally be configured in the form of a column, and fluids containing ligand are passed through the column one or more times to allow ligand to bind to the receptor polypeptide. The ligand is then eluted using changes in salt concentration, chaotropic agents (guanidine HCl), or pH to disrupt ligand-receptor binding.

[0183] An assay system that uses a ligand-binding receptor (or an antibody, one member of a complement/anti-complement pair) or a binding fragment thereof, and a commercially available biosensor instrument (BlAcore, Pharmacia Biosensor, Piscataway, N.J.) may be advantageously employed. Such receptor, antibody, member of a complement/anti-complement pair or fragment is immobilized onto the surface of a receptor chip. Use of this instrument is disclosed by Karlsson, J. Immunol. Methods 145:229-40 (1991) and Cunningham and Wells, J. Mol. Biol. 234:554-63 (1993). A receptor, antibody, member or fragment is covalently attached, using amine or sulfhydryl chemistry, to dextran fibers that are attached to gold film within the flow cell. A test sample is passed through the cell. If a ligand, epitope, or opposite member of the complement/anti-complement pair is present in the sample, it will bind to the immobilized receptor, antibody or member, respectively, causing a change in the refractive index of the medium, which is detected as a change in surface plasmon resonance of the gold film. This system allows the determination of on- and off-rates, from which binding affinity can be calculated, and assessment of stoichiometry of binding. Alternatively, ligand/receptor binding can be analyzed using SELDI(™) technology (Ciphergen, Inc., Palo Alto, Calif.).

[0184] Ligand-binding receptor polypeptides can also be used within other assay systems known in the art. Such systems include Scatchard analysis for determination of binding affinity (see Scatchard, Ann. NY Acad. Sci. 51: 660-72 (1949)) and calorimetric assays (Cunningham et al., Science 253:545-48 (1991); and Cunningham et al., Science 245:821-25 (1991)).

[0185] The present invention also provides an antibody that specifically binds to a polypeptide or at least at portion of a multimeric cytokine receptor as described herein.

[0186] Zcytor17 multimeric cytokine receptors can also be used to prepare antibodies that bind to epitopes, peptides or polypeptides thereof. The multimeric cytokine receptor or a fragment thereof serves as an antigen (immunogen) to inoculate an animal and elicit an immune response. One of skill in the art would recognize that antigenic, epitope-bearing polypeptides may contain a sequence of at least 6, preferably at least 9, and more preferably at least 15 to about 30 contiguous amino acid residues of a polypeptide(s) of the multimeric cytokine receptor, such as zcytor17 (SEQ ID NO: 111), OSMRbeta (SEQ ID NO: 7), and/or WSX-1 (SEQ ID NO: 9). Polypeptides comprising a larger portion of a multimeric cytokine receptor, i.e., from 30 to 100 residues up to the entire length of the amino acid sequence are included. Antigens or immunogenic epitopes can also include attached tags, adjuvants, carriers and vehicles, as described herein.

[0187] Antibodies from an immune response generated by inoculation of an animal with these antigens can be isolated and purified as described herein. Methods for preparing and isolating polyclonal and monoclonal antibodies are well known in the art. See, for example, Current Protocols in Immunology, Cooligan, et al. (eds.), National Institutes of Health, John Wiley and Sons, Inc., 1995; Sambrook et al., Molecular Cloning: A Laboratory Manual, Second Edition, Cold Spring Harbor, N.Y., 1989; and Hurrell, J. G. R., Ed., Monoclonal Hybridoma Antibodies: Techniques and Applications, CRC Press, Inc., Boca Raton, Fla., 1982.

[0188] As would be evident to one of ordinary skill in the art, polyclonal antibodies can be generated from inoculating a variety of warm-blooded animals such as horses, cows, goats, sheep, dogs, chickens, rabbits, mice, and rats with a multimeric cytokine receptor or a fragment thereof. The immunogenicity of a multimeric cytokine receptor may be increased through the use of an adjuvant, such as alum (aluminum hydroxide) or Freund's complete or incomplete adjuvant. Multimeric cytokine receptors useful for immunization also include fusion polypeptides, such as fusions of zcytor17, OSMRbeta, and/or WSX-1, or a portion thereof with an immunoglobulin polypeptide or with maltose binding protein. The polypeptide immunogen may be a full-length molecule or a portion thereof. If the polypeptide portion is “hapten-like”, such portion may be advantageously joined or linked to a macromolecular carrier (such as keyhole limpet hemocyanin (KLH), bovine serum albumin (BSA) or tetanus toxoid) for immunization.

[0189] As used herein, the term “antibodies” includes polyclonal antibodies, affinity-purified polyclonal antibodies, monoclonal antibodies, and antigen-binding fragments, such as F(ab′)₂ and Fab proteolytic fragments. Genetically engineered intact antibodies or fragments, such as chimeric antibodies, Fv fragments, single chain antibodies and the like, as well as synthetic antigen-binding peptides and polypeptides, are also included. Non-human antibodies may be humanized by grafting non-human CDRs onto human framework and constant regions, or by incorporating the entire non- human variable domains (optionally “cloaking” them with a human-like surface by replacement of exposed residues, wherein the result is a “veneered” antibody). In some instances, humanized antibodies may retain non-human residues within the human variable region framework domains to enhance proper binding characteristics. Through humanizing antibodies, biological half-life may be increased, and the potential for adverse immune reactions upon administration to humans is reduced. Moreover, human antibodies can be produced in transgenic, non-human animals that have been engineered to contain human immunoglobulin genes as disclosed in WIPO Publication WO 98/24893. It is preferred that the endogenous immunoglobulin genes in these animals be inactivated or eliminated, such as by homologous recombination.

[0190] Antibodies are considered to be specifically binding if: 1) they exhibit a threshold level of binding activity, and 2) they do not significantly cross-react with related polypeptide molecules. A threshold level of binding is determined if anti- multimeric cytokine receptor antibodies herein bind to a multimeric cytokine receptor, peptide or epitope with an affinity at least 10-fold greater than the binding affinity to control (non-multimeric cytokine receptor) protein. It is preferred that the antibodies exhibit a binding affinity (K_(a)) of 10⁶M⁻¹ or greater, preferably 10⁷ M⁻¹ or greater, more preferably 10⁸ M⁻¹ or greater, and most preferably 10⁹ M⁻¹ or greater. The binding affinity of an antibody can be readily determined by one of ordinary skill in the art, for example, by Scatchard analysis (Scatchard, G., Ann. NY Acad. Sci. 51: 660-672 (1949)).

[0191] Whether anti-multimeric cytokine receptor antibodies do not significantly cross-react with related polypeptide molecules is shown, for example, by the antibody detecting zcytor17 multimeric cytokine receptor but not known related polypeptides using a standard Western blot analysis (Ausubel et al., ibid.). Examples of known related polypeptides are those disclosed in the prior art, such as known orthologs, and paralogs, and similar known members of a protein family. Screening can also be done using non-human multimeric cytokine receptor, and multimeric cytokine receptor mutant polypeptides. Moreover, antibodies can be “screened against” known related polypeptides, to isolate a population that specifically binds to the multimeric cytokine receptor. For example, antibodies raised to multimeric cytokine receptor are adsorbed to related polypeptides adhered to insoluble matrix; antibodies specific to multimeric cytokine receptor will flow through the matrix under the proper buffer conditions. Screening allows isolation of polyclonal and monoclonal antibodies non-crossreactive to known closely related polypeptides (Antibodies: A Laboratory Manual, Harlow and Lane (eds.), Cold Spring Harbor Laboratory Press, 1988; Current Protocols in Immunology, Cooligan, et al. (eds.), National Institutes of Health, John Wiley and Sons, Inc., 1995). Screening and isolation of specific antibodies is well known in the art. See, Fundamental Immunology, Paul (eds.), Raven Press, 1993; Getzoff et al., Adv. in Immunol. 43: 1-98, 1988; Monoclonal Antibodies: Principles and Practice, Goding, J. W. (eds.), Academic Press Ltd., 1996; Benjamin et al., Ann. Rev. Immunol. 2: 67-101, 1984. Specifically binding anti-multimeric cytokine receptor antibodies can be detected by a number of methods in the art, and disclosed below.

[0192] A variety of assays known to those skilled in the art can be utilized to detect antibodies which bind to multimeric cytokine receptor proteins or polypeptides.

[0193] Exemplary assays are described in detail in Antibodies: A Laboratory Manual, Harlow and Lane (Eds.), Cold Spring Harbor Laboratory Press, 1988. Representative examples of such assays include: concurrent immunoelectrophoresis, radioimmunoassay, radioimmuno-precipitation, enzyme-linked immunosorbent assay (ELISA), dot blot or Western blot assay, inhibition or competition assay, and sandwich assay. In addition, antibodies can be screened for binding to wild-type versus mutant multimeric cytokine receptor protein or polypeptide.

[0194] Within another aspect the present invention provides an antibody produced by the method as disclosed above, wherein the antibody binds to at least a portion of a multimer cytokine receptor comprising at least a portion of SEQ ID NO: 111, SEQ ID NO: 109, or SEQ ID NO: 5. In one embodiment, the antibody disclosed above specifically binds to a polypeptide shown in SEQ ID NO: 111, SEQ ID NO: 109, or SEQ ID NO: 5. In another embodiment, the antibody can be a monoclonal antibody or a polyclonal antibody.

[0195] Antibodies to multimeric cytokine receptor may be used for tagging cells that express multimeric cytokine receptor; for isolating multimeric cytokine receptor by affinity purification; for diagnostic assays for determining circulating levels of multimeric cytokine receptor; for detecting or quantitating soluble multimeric cytokine receptor as a marker of underlying pathology or disease; in analytical methods employing FACS; for screening expression libraries; for generating anti-idiotypic antibodies; and as neutralizing antibodies or as antagonists to block multimeric cytokine receptor activity in vitro and in vivo. Suitable direct tags or labels include radionuclides, enzymes, substrates, cofactors, inhibitors, fluorescent markers, chemiluminescent markers, magnetic particles and the like; indirect tags or labels may feature use of biotin-avidin or other complement/anti-complement pairs as intermediates. Antibodies herein may also be directly or indirectly conjugated to drugs, toxins, radionuclides and the like, and these conjugates used for in vivo diagnostic or therapeutic applications. Moreover, antibodies to multimeric cytokine receptor or fragments thereof may be used in vitro to detect denatured multimeric cytokine receptor or fragments thereof in assays, for example, Western Blots or other assays known in the art.

[0196] Suitable detectable molecules may be directly or indirectly attached to the multimeric cytokine receptor or antibody, and include radionuclides, enzymes, substrates, cofactors, inhibitors, fluorescent markers, chemiluminescent markers, magnetic particles and the like. Suitable cytotoxic molecules may be directly or indirectly attached to the polypeptide or antibody, and include bacterial or plant toxins (for instance, diphtheria, toxin, saporin, Pseudomonas exotoxin, ricin, abrin and the like), as well as therapeutic radionuclides, such as iodine-131, rhenium-188 or yttrium-90 (either directly attached to the polypeptide or antibody, or indirectly attached through means of a chelating moiety, for instance). Multimeric cytokine receptors or antibodies may also be conjugated to cytotoxic drugs, such as adriamycin. For indirect attachment of a detectable or cytotoxic molecule, the detectable or cytotoxic molecule can be conjugated with a member of a complementary/anticomplementary pair, where the other member is bound to the polypeptide or antibody portion. For these purposes, biotin/streptavidin is an exemplary complementary/anticomplementary pair.

[0197] A soluble multimeric cytokine receptor can also act as zcytor17lig “antagonists” to block zcytor17lig binding and signal transduction in vitro and in vivo. These anti-zcytor17lig binding proteins would be useful for inhibiting zcytor17lig activity or protein-binding.

[0198] Polypeptide-toxin fusion proteins or antibody-toxin fusion proteins can be used for targeted cell or tissue inhibition or ablation (for instance, to treat cancer cells or tissues). Alternatively, if the polypeptide has multiple functional domains (i.e., an activation domain or a receptor binding domain, plus a targeting domain), a fusion protein including only the targeting domain may be suitable for directing a detectable molecule, a cytotoxic molecule or a complementary molecule to a cell or tissue type of interest. In instances where the domain only fusion protein includes a complementary molecule, the anti-complementary molecule can be conjugated to a detectable or cytotoxic molecule. Such domain-complementary molecule fusion proteins thus represent a generic targeting vehicle for cell/tissue-specific delivery of generic anti-complementary-detectable/cytotoxic molecule conjugates.

[0199] Moreover, inflammation is a protective response by an organism to fend off an invading agent. Inflammation is a cascading event that involves many cellular and humoral mediators. On one hand, suppression of inflammatory responses can leave a host immunocompromised; however, if left unchecked, inflammation can lead to serious complications including chronic inflammatory diseases (e.g., rheumatoid arthritis, multiple sclerosis, inflammatory bowel disease and the like), septic shock and multiple organ failure. Importantly, these diverse disease states share common inflammatory mediators. The collective diseases that are characterized by inflammation have a large impact on human morbidity and mortality. Therefore it is clear that anti-inflammatory antibodies and binding polypeptides, such as anti-zcytor17lig antibodies and binding polypeptides described herein, could have crucial therapeutic potential for a vast number of human and animal diseases, from asthma and allergy to autoimmunity and septic shock. As such, use of anti-inflammatory anti zcytor17lig antibodies and binding polypeptides described herein can be used therapeutically as zcytor17lig antagonists described herein, particularly in diseases such as arthritis, endotoxemia, inflammatory bowel disease, psoriasis, related disease and the like.

[0200] 1. Arthritis

[0201] Arthritis, including osteoarthritis, rheumatoid arthritis, arthritic joints as a result of injury, and the like, are common inflammatory conditions which would benefit from the therapeutic use of anti-inflammatory antibodies and binding polypeptides, such as anti-zcytor17lig antibodies and binding polypeptides of the present invention. For example, rheumatoid arthritis (RA) is a systemic disease that affects the entire body and is one of the most common forms of arthritis. It is characterized by the inflammation of the membrane lining the joint, which causes pain, stiffness, warmth, redness and swelling.) Inflammatory cells release enzymes that may digest bone and cartilage. As a result of rheumatoid arthritis, the inflamed joint lining, the synovium, can invade and damage bone and cartilage leading to joint deterioration and severe pain amongst other physiologic effects. The involved joint can lose its shape and alignment, resulting in pain and loss of movement.

[0202] Rheumatoid arthritis (RA) is an immune-mediated disease particularly characterized by inflammation and subsequent tissue damage leading to severe disability and increased mortality. A variety of cytokines are produced locally in the rheumatoid joints. Numerous studies have demonstrated that IL-1 and TNF-alpha, two prototypic pro-inflammatory cytokines, play an important role in the mechanisms involved in synovial inflammation and in progressive joint destruction. Indeed, the administration of TNF-alpha and IL-1 inhibitors in patients with RA has led to a dramatic improvement of clinical and biological signs of inflammation and a reduction of radiological signs of bone erosion and cartilage destruction. However, despite these encouraging results, a significant percentage of patients do not respond to these agents, suggesting that other mediators are also involved in the pathophysiology of arthritis (Gabay, Expert. Opin. Biol. Ther. 2(2):135-149, 2002). One of those mediators could be zcytor17lig, and as such a molecule that binds or inhibits zcytor17lig, such as anti zcytor17lig antibodies or binding partners, could serve as a valuable therapeutic to reduce inflammation in rheumatoid arthritis, and other arthritic diseases.

[0203] There are several animal models for rheumatoid arthritis known in the art. For example, in the collagen-induced arthritis (CIA) model, mice develop chronic inflammatory arthritis that closely resembles human rheumatoid arthritis. Since CIA shares similar immunological and pathological features with RA, this makes it an ideal model for screening potential human anti-inflammatory compounds. The CIA model is a well-known model in mice that depends on both an immune response, and an inflammatory response, in order to occur. The immune response comprises the interaction of B-cells and CD4+ T-cells in response to collagen, which is given as antigen, and leads to the production of anti-collagen antibodies. The inflammatory phase is the result of tissue responses from mediators of inflammation, as a consequence of some of these antibodies cross-reacting to the mouse's native collagen and activating the complement cascade. An advantage in using the CIA model is that the basic mechanisms of pathogenesis are known. The relevant T-cell and B-cell epitopes on type II collagen have been identified, and various immunological (e.g., delayed-type hypersensitivity and anti-collagen antibody) and inflammatory (e.g., cytokines, chemokines, and matrix-degrading enzymes) parameters relating to immune-mediated arthritis have been determined, and can thus be used to assess test compound efficacy in the CIA model (Wooley, Curr. Opin. Rheum. 3:407-20, 1999; Williams et al., Immunol. 89:9784-788, 1992; Myers et al., Life Sci. 61:1861-78, 1997; and Wang et al., Immunol. 92:8955-959, 1995).

[0204] The administration of soluble zcytor17 comprising polypeptides (including heterodimeric and multimeric receptors described herein), such as zcytor17-Fc4 or other zcytor17 soluble and fusion proteins to these CIA model mice was used to evaluate the use of zcytor17 to ameliorate symptoms and alter the course of disease. As a molecule that modulates immune and inflammatory response, zcytor17lig, may induce production of SAA, which is implicated in the pathogenesis of rheumatoid arthritis, zcytor17lig antagonists may reduce SAA activity in vitro and in vivo, the systemic or local administration of zcytor17lig antagonists such as anti-zcytor17lig antibodies or binding partners, zcytor17 comprising polypeptides (including heterodimeric and multimeric receptors described herein), such as zcytor17-Fc4 or other zcytor17 soluble and fusion proteins can potentially suppress the inflammatory response in RA. Other potential therapeutics include zcytor17 polypeptides, soluble heterodimeric and multimeric receptor polypeptides, or anti zcytor17lig antibodies or binding partners of the present invention, and the like.

[0205] 2. Endotoxemia

[0206] Endotoxemia is a severe condition commonly resulting from infectious agents such as bacteria and other infectious disease agents, sepsis, toxic shock syndrome, or in immunocompromised patients subjected to opportunistic infections, and the like. Therapeutically useful of anti-inflammatory antibodies and binding polypeptides, such as anti-zcytor17lig antibodies and binding polypeptides of the present invention, could aid in preventing and treating endotoxemia in humans and animals. Other potential therapeutics include zcytor17 polypeptides, soluble heterodimeric and multimeric receptor polypeptides, or anti zcytor17lig antibodies or binding partners of the present invention, and the like, could serve as a valuable therapeutic to reduce inflammation and pathological effects in endotoxemia.

[0207] Lipopolysaccharide (LPS) induced endotoxemia engages many of the proinflammatory mediators that produce pathological effects in the infectious diseases and LPS induced endotoxemia in rodents is a widely used and acceptable model for studying the pharmacological effects of potential pro-inflammatory or immunomodulating agents. LPS, produced in gram-negative bacteria, is a major causative agent in the pathogenesis of septic shock (Glausner et al., Lancet 338:732, 1991). A shock-like state can indeed be induced experimentally by a single injection of is LPS into animals. Molecules produced by cells responding to LPS can target pathogens directly or indirectly. Although these biological responses protect the host against invading pathogens, they may also cause harm. Thus, massive stimulation of innate immunity, occurring as a result of severe Gram-negative bacterial infection, leads to excess production of cytokines and other molecules, and the development of a fatal syndrome, septic shock syndrome, which is characterized by fever, hypotension, disseminated intravascular coagulation, and multiple organ failure (Dumitru et al. Cell 103:1071-1083, 2000).

[0208] These toxic effects of LPS are mostly related to macrophage activation leading to the release of multiple inflammatory mediators. Among these mediators, TNF appears to play a crucial role, as indicated by the prevention of LPS toxicity by the administration of neutralizing anti-TNF antibodies (Beutler et al., Science 229:869, 1985). It is well established that lug injection of E. coli LPS into a C57B1/6 mouse will result in significant increases in circulating IL-6, TNF-alpha, IL-1, and acute phase proteins (for example, SAA) approximately 2 hours post injection. The toxicity of LPS appears to be mediated by these cytokines as passive immunization against these mediators can result in decreased mortality (Beutler et al., Science 229:869, 1985). The potential immunointervention strategies for the prevention and/or treatment of septic shock include anti-TNF mAb, IL-1 receptor antagonist, LIF_(c) IL-10, and G-CSF. Since LPS induces the production of pro- inflammatory factors possibly contributing to the pathology of endotoxemia, the neutralization of zcytor17lig activity, SAA or other pro-inflammatory factors by antagonizing zcytor17lig polypeptide can be used to reduce the symptoms of endotoxemia, such as seen in endotoxic shock. Other potential therapeutics include zcytor17 polypeptides, soluble heterodimeric and multimeric receptor polypeptides, or anti-zcytor17lig antibodies or binding partners of the present invention, and the like.

[0209] 3 Inflammatory Bowel Disease. IBD

[0210] In the United States approximately 500,000 people suffer from Inflammatory Bowel Disease (IBD) which can affect either colon and rectum (Ulcerative colitis) or both, small and large intestine (Crohn's Disease). The pathogenesis of these diseases is unclear, but they involve chronic inflammation of the affected tissues. Potential therapeutics include zcytor17 polypeptides, soluble heterodimeric and multimeric receptor polypeptides, or anti-zcytor17lig antibodies or binding partners of the present invention, and the like, could serve as a valuable therapeutic to reduce inflammation and pathological effects in IBD and related diseases.

[0211] Ulcerative colitis (UC) is an inflammatory disease of the large intestine, commonly called the colon, characterized by inflammation and ulceration of the mucosa or innermost lining of the colon. This inflammation causes the colon to empty frequently, resulting in diarrhea. Symptoms include loosening of the stool and associated abdominal cramping, fever and weight loss. Although the exact cause of UC is unknown, recent research suggests that the body's natural defenses are operating against proteins in the body which the body thinks are foreign (an “autoimmune reaction”). Perhaps because they resemble bacterial proteins in the gut, these proteins may either instigate or stimulate the inflammatory process that begins to destroy the lining of the colon. As the lining of the colon is destroyed, ulcers form releasing mucus, pus and blood. The disease usually begins in the rectal area and may eventually extend through the entire large bowel. Repeated episodes of inflammation lead to thickening of the wall of the intestine and rectum with scar tissue. Death of colon tissue or sepsis may occur with severe disease. The symptoms of ulcerative colitis vary in severity and their onset may be gradual or sudden. Attacks may be provoked by many factors, including respiratory infections or stress.

[0212] Although there is currently no cure for UC available, treatments are focused on suppressing the abnormal inflammatory process in the colon lining. Treatments including corticosteroids immunosuppressives (eg. azathioprine, mercaptopurine, and methotrexate) and aminosalicytates are available to treat the disease. However, the long-term use of immunosuppressives such as corticosteroids and azathioprine can result in serious side effects including thinning of bones, cataracts, infection, and liver and bone marrow effects. In the patients in whom current therapies are not successful, surgery is an option. The surgery involves the removal of the entire colon and the rectum.

[0213] There are several animal models that can partially mimic chronic ulcerative colitis. The most widely used model is the 2,4,6-trinitrobenesulfonic acid/ethanol (TNBS) induced colitis model, which induces chronic inflammation and ulceration in the colon. When TNBS is introduced into the colon of susceptible mice via intra-rectal instillation, it induces T-cell mediated immune response in the colonic mucosa, in this case leading to a massive mucosal inflammation characterized by the dense infiltration of T-cells and macrophages throughout the entire wall of the large bowel. Moreover, this histopathologic picture is accompanies by the clinical picture of progressive weight loss (wasting), bloody diarrhea, rectal prolapse, and large bowel wall thickening (Neurath et al. Intern. Rev. Immunol. 19:51-62, 2000).

[0214] Another colitis model uses dextran sulfate sodium (DSS), which induces an acute colitis manifested by bloody diarrhea, weight loss, shortening of the colon and mucosal ulceration with neutrophil infiltration. DSS-induced colitis is characterized histologically by infiltration of inflammatory cells into the lamina propria, with lymphoid hyperplasia, focal crypt damage, and epithelial ulceration. These changes are thought to develop due to a toxic effect of DSS on the epithelium and by phagocytosis of lamina propria cells and production of TNF-alpha and IFN-gamma. Despite its common use, several issues regarding the mechanisms of DSS about the relevance to the human disease remain unresolved. DSS is regarded as a T cell-independent model because it is observed in T cell-deficient animals such as SCID mice.

[0215] The administration of anti-zcytor17lig antibodies or binding partners, soluble zcytor17 comprising polypeptides (including heterodimeric and multimeric receptors), such as zcytor17-Fc4 or other zcytor17 soluble and fusion proteins to these TNBS or DSS models can be used to evaluate the use of zcytor17lig antagonists to ameliorate symptoms and alter the course of gastrointestinal disease. Zcytor17lig may play a role in the inflammatory response in colitis, and the neutralization of zcytor17lig activity by administrating zcytor17lig antagonists is a potential therapeutic approach for IBD. Other potential therapeutics include zcytor17 polypeptides, soluble heterodimeric and multimeric receptor polypeptides, or anti-zcytor17lig antibodies or binding partners of the present invention, and the like.

[0216] 4. Psoriasis

[0217] Psoriasis is a chronic skin condition that affects more than seven million Americans. Psoriasis occurs when new skin cells grow abnormally, resulting in inflamed, swollen, and scaly patches of skin where the old skin has not shed quickly enough. Plaque psoriasis, the most common form, is characterized by inflamed patches of skin (“lesions”) topped with silvery white scales. Psoriasis may be limited to a few plaques or involve moderate to extensive areas of skin, appearing most commonly on the scalp, knees, elbows and trunk. Although it is highly visible, psoriasis is not a contagious disease. The pathogenesis of the diseases involves chronic inflammation of the affected tissues. Zcytor17 polypeptides, soluble heterodimeric and multimeric receptor polypeptides, or anti-zcytor17lig antibodies or binding partners of the present invention, and the like, could serve as a valuable therapeutic to reduce inflammation and pathological effects in psoriasis, other inflammatory skin diseases, skin and mucosal allergies, and related diseases.

[0218] Psoriasis is a T-cell mediated inflammatory disorder of the skin that can cause considerable discomfort. It is a disease for which there is no cure and affects people of all ages. Psoriasis affects approximately two percent of the populations of European and North America. Although individuals with mild psoriasis can often control their disease with topical agents, more than one million patients worldwide require ultraviolet or systemic immunosuppressive therapy. Unfortunately, the inconvenience and risks of ultraviolet radiation and the toxicities of many therapies limit their long-term use. Moreover, patients usually have recurrence of psoriasis, and in some cases rebound, shortly after stopping immunosuppressive therapy.

[0219] Differentiation is a progressive and dynamic process, beginning with pluripotent stem cells and ending with terminally differentiated cells. Pluripotent stem cells that can regenerate without commitment to a lineage express a set of differentiation markers that are lost when commitment to a cell lineage is made. Progenitor cells express a set of differentiation markers that may or may not continue to be expressed as the cells progress down the cell lineage pathway toward maturation. Differentiation markers that are expressed exclusively by mature cells are usually functional properties such as cell products, enzymes to produce cell products, and receptors. The stage of a cell population's differentiation is monitored by identification of markers present in the cell population.

[0220] There is evidence to suggest that factors that stimulate specific cell types down a pathway towards terminal differentiation or dedifferentiation affect the entire cell population originating from a common precursor or stem cell.

[0221] A multimeric cytokine receptor of the present invention can be useful for stimulating proliferation, activation, differentiation and/or induction or inhibition of specialized cell function of cells of the involved homeostasis of the hematopoiesis and immune function. In particular, multimeric cytokine receptors as described herein are useful for stimulating proliferation, activation, differentiation, induction or inhibition of specialized cell functions of cells of the hematopoietic lineages, including, but not limited to, T cells, B cells, monocytes/macrophages, NK cells, neutrophils, endothelial cells, fibroblasts, eosinophils, chondrocytes, mast cells, langerhan cells, monocytes, and macrophages, as well as epithelial cells. Epithelial cells include, for example, ameloblasts, chief cells, chromatophores, enterochramaffin cells, enterochromaffin-like cells, goblet cells, granulosa cells, keratinocytes, dendritic cells, labyrinth supporting cells, melanocytes, merkel cells, paneth cells, parietal cells, sertoli cells, and the like.

[0222] The present invention also provides a method for reducing hematopoietic cells and hematopoietic cell progenitors of a mammal. The method includes culturing bone marrow or peripheral blood cells with a composition comprising an effective amount of a soluble multimeric cytokine receptor to produce a decrease in the number of lymphoid cells in the bone marrow or peripheral blood cells as compared to bone marrow or peripheral blood cells cultured in the absence of the multimeric cytokine receptor. The hematopoietic cells and hematopoietic cell progenitors can be lymphoid cells, such as monocytic cells, macrophages, or T cells.

[0223] The present invention also provides a method of inhibiting an immune response in a mammal exposed to an antigen or pathogen. The method includes (a) determining directly or indirectly the level of antigen or pathogen present in the mammal; (b) administering a composition comprising a soluble multimeric cytokine receptor in an acceptable pharmaceutical vehicle; (c) determining directly or indirectly the level of antigen or pathogen in the mammal; and (d) comparing the level of the antigen or pathogen in step (a) to the antigen or pathogen level in step (c), wherein a change in the level is indicative of inhibiting an immune response. The method may further include (e) re-administering a composition comprising a multimeric cytokine receptor in an acceptable pharmaceutical vehicle; (f) determining directly or indirectly the level of antigen or pathogen in the mammal; and (g) comparing the number of the antigen or pathogen level in step (a) to the antigen level in step (f), wherein a change in the level is indicative of inhibiting an immune response.

[0224] Alternatively, the method can include (a) determining a level of an antigen- or pathogen-specific antibody; (b) administering a composition comprising a soluble multimeric cytokine receptor in an acceptable pharmaceutical vehicle; (c) determining a post administration level of antigen- or pathogen-specific antibody; (d) comparing the level of antibody in step (a) to the level of antibody in step (c), wherein a decrease in antibody level is indicative of inhibiting an immune response.

[0225] Zcytor17lig was isolated from tissue known to have important immunological function and which contain cells that play a role in the immune system. Zcytor17lig is expressed in CD3+ selected, activated peripheral blood cells, and it has been shown that zcytor17lig expression increases after T cell activation. Moreover, results of experiments described in the Examples section herein suggest that a multimeric or heterodimeric cytokine receptor of the present invention can have an effect on the growth/expansion of monocytes/macrophages, T-cells, B-cells, NK cells and/or differentiated state of monocytes/macrophages, T-cells, B-cells, NK cells or these cells' progenitors. Factors that both stimulate proliferation of hematopoietic progenitors and activate mature cells are generally known, however, proliferation and activation can also require additional growth factors. For example, it has been shown that IL-7 and Steel Factor (c-kit ligand) were required for colony formation of NK progenitors. IL-15 plus IL-2 in combination with IL-7 and Steel Factor was more effective (Mrózek et al., Blood 87:2632-2640, 1996). However, unidentified cytokines may be necessary for proliferation of specific subsets of NK cells and/or NK progenitors (Robertson et. al., Blood 76:2451-2438, 1990). Similarly, zcytor17lig may act alone or in concert or synergy with other cytokines to enhance growth, proliferation expansion and modification of differentiation of monocytes/macrophages, T-cells, B-cells or NK cells.

[0226] Assays measuring differentiation include, for example, measuring cell markers associated with stage-specific expression of a tissue, enzymatic activity, functional activity or morphological changes (Watt, FASEB, 5:281-284 (1991); Francis, Differentiation 57:63-75 (1994); and Raes, Adv. Anim. Cell Biol. Technol. Bioprocesses, 161-171 (1989)). Alternatively, zcytor17lig polypeptide itself can serve as an additional cell-surface or secreted marker associated with stage-specific expression of a tissue. As such, direct measurement of zcytor17lig polypeptide, or its loss of expression in a tissue as it differentiates, can serve as a marker for differentiation of tissues.

[0227] Similarly, direct measurement of zcytor17lig polypeptide, or its loss of expression in a tissue can be determined in a tissue or in cells as they undergo tumor progression. Increases in invasiveness and motility of cells, or the gain or loss of expression of zcytor17lig in a pre-cancerous or cancerous condition, in comparison to normal tissue, can serve as a diagnostic for transformation, invasion and metastasis in tumor progression. As such, knowledge of a tumor's stage of progression or metastasis will aid the physician in choosing the most proper therapy, or aggressiveness of treatment, for a given individual cancer patient. Methods of measuring gain and loss of expression (of either mRNA or protein) are well known in the art and described herein and can be applied to zcytor17lig expression. For example, appearance or disappearance of polypeptides that regulate cell motility can be used to aid diagnosis and prognosis of prostate cancer (Banyard, J. and Zetter, B. R., Cancer and Metast. Rev. 17:449-458, 1999). As an effector of cell motility, zcytor17lig gain or loss of expression may serve as a diagnostic for lymphoid, B-cell, epithelial, hematopoietic and other cancers.

[0228] Moreover, the activity and effect of zcytor17lig on tumor progression and metastasis can be measured in vivo. Several syngeneic mouse models have been developed to study the influence of polypeptides, compounds or other treatments on tumor progression. In these models, tumor cells passaged in culture are implanted into mice of the same strain as the tumor donor. The cells will develop into tumors having similar characteristics in the recipient mice, and metastasis will also occur in some of the models. Appropriate tumor models for our studies include the Lewis lung carcinoma (ATCC No. CRL-1642) and B16 melanoma (ATCC No. CRL-6323), amongst others. These are both commonly used tumor lines, syngeneic to the C57BL6/J mouse, that are readily cultured and manipulated in vitro. Tumors resulting from implantation of either of these cell lines are capable of metastasis to the lung in C57BL6/J mice. The Lewis lung carcinoma model has recently been used in mice to identify an inhibitor of angiogenesis (O'Reilly M S, et al. Cell 79: 315-328,1994). C57BL6/J mice are treated with an experimental agent either through daily injection of recombinant protein, agonist or antagonist or a one time injection of recombinant adenovirus. Three days following this treatment, 10⁵ to 10⁶ cells are implanted under the dorsal skin. Alternatively, the cells themselves may be infected with recombinant adenovirus, such as one expressing zcytor17lig, before implantation so that the protein is synthesized at the tumor site or intracellularly, rather than systemically. The mice normally develop visible tumors within 5 days. The tumors are allowed to grow for a period of up to 3 weeks, during which time they may reach a size of 1500-1800 mm³ in the control treated group. Tumor size and body weight are carefully monitored throughout the experiment. At the time of sacrifice, the tumor is removed and weighed along with the lungs and the liver. The lung weight has been shown to correlate well with metastatic tumor burden. As an additional measure, lung surface metastases are counted. The resected tumor, lungs and liver are prepared for histopathological examination, immunohistochemistry, and in situ hybridization, using methods known in the art and described herein. The influence of the expressed polypeptide in question, e.g., zcytor17lig, on the ability of the tumor to recruit vasculature and undergo metastasis can thus be assessed. In addition, aside from using adenovirus, the implanted cells can be transiently transfected with zcytor17lig. Use of stable zcytor17lig transfectants as well as use of induceable promoters to activate zcytor17lig expression in vivo are known in the art and can be used in this system to assess zcytor17lig induction of metastasis. Moreover, purified zcytor17lig or zcytor17lig conditioned media can be directly injected in to this mouse model, and hence be used in this system. For general reference see, O'Reilly M S, et al. Cell 79:315-328, 1994; and Rusciano D, et al. Murine Models of Liver Metastasis. Invasion Metastasis 14:349-361, 1995.

[0229] A soluble multimeric cytokine receptor of the present invention or antibodies thereto may be useful in treating tumorgenesis, and therefore would be useful in the treatment of cancer. Zcytor17lig is expressed in activated T-cells, monocytes and macrophages, and is linked to a region of the human chromosome wherein translocations are common in leukemias. Moreover, the zcytor17lig is shown to act through a cytokine receptor, zcytor17 multimeric cytokine receptor, which is also expressed in activated T-cells, monocytes and macrophages. Over stimulation of activated T-cells, monocytes and macrophages by zcytor17lig could result in a human disease state such as an immune cell cancer. As such, identifying zcytor17lig expression, polypeptides (e.g., by anti-zcytor17lig antibodies, zcytor17 soluble multimeric cytokine receptors (e.g., zcytor17 receptor, heterodimers (e.g., zcytor17/OSMRbeta, zcytor17/WSX-1), multimers (e.g., zcytor17/OSMRbeta/WSX-1)), or other zcytor17lig binding partners) can serve as a diagnostic, and can serve as antagonists of zcytor17lig proliferative activity. The ligand could be administered in combination with other agents already in use including both conventional chemotherapeutic agents as well as immune modulators such as interferon alpha. Alpha/beta interferons have been shown to be effective in treating some leukemias and animal disease models, and the growth inhibitory effects of interferon-alpha and zcytor17lig may be additive.

[0230] NK cells are thought to play a major role in elimination of metastatic tumor cells and patients with both metastases and solid tumors have decreased levels of NK cell activity (Whiteside et. al., Curr. Top. Microbiol. Immunol. 230:221-244, 1998). An agent that stimulates NK cells would be useful in the elimination of tumors.

[0231] The present invention provides a method of reducing proliferation of a neoplastic monocytes/macrophages comprising administering to a mammal with a monocyte/macrophage neoplasm an amount of a composition including a soluble multimeric cytokine receptor or antibody thereto sufficient to reduce proliferation of the neoplastic monocytes/macrophages.

[0232] The present invention provides a method for inhibiting activation or differentiation of monocytes/macrophages. Monocytes are incompletely differentiated cells that migrate to various tissues where they mature and become macrophages. Macrophages play a central role in the immune response by presenting antigen to lymphocytes and play a supportive role as accessory cells to lymphocytes by secreting numerous cytokines. Macrophages can internalize extracellular molecules and upon activation have an increased ability to kill intracellular microorganisms and tumor cells. Activated macrophages are also involved in stimulating acute or local inflammation.

[0233] In another aspect, the present invention provides a method of reducing proliferation of a neoplastic B or T-cells comprising administering to a mammal with a B or T cell neoplasm an amount of a composition including a soluble multimeric cytokine receptor sufficient to reducing proliferation of the neoplastic monocytes/macrophages. Furthermore, the zcytor17lig antagonist can be a ligand/toxin fusion protein.

[0234] A zcytor17 multimeric cytokine receptor-saporin fusion toxin may be employed against a similar set of leukemias and lymphomas, extending the range of leukemias that can be treated with a cytokine antagonsist. For example, such leukemias can be those that over-express zcytor17 receptors (e.g., zcytor17 receptor, heterodimers (e.g., zcytor17/OSMRbeta, zcytor17/WSX-1), multimers (e.g., zcytor17/OSMRbeta/WSX)). Fusion toxin mediated activation of the zcytor17 receptor, zcytor17 receptor heterodimers or multimers (e.g., zcytor17/OSMRbeta, zcytor17/WSX-1 or zcytor17/WSX-1/OSMR) provides two independent means to inhibit the growth of the target cells, the first being identical to the effects seen by the ligand alone, and the second due to delivery of the toxin through receptor internalization. The lymphoid and monocyte restricted expression pattern of the zcytor17 receptor suggests that the ligand-saporin conjugate can be tolerated by patients.

[0235] The tissue distribution of receptors for a given cytokine offers a strong indication of the potential sites of action of that cytokine. Expression of zcytor17 was seen in monocytes and B-cells, with a dramatic increase of expression upon activation for CD3+, CD4+, and CD8+ T-cells. In addition, two monocytic cell lines, THP-1 (Tsuchiya et al., Int. J. Cancer 26:171-176, 1980) and U937 (Sundstrom et al., Int. J. Cancer 17:565-577, 1976), were also positive for zcytor17 expression.

[0236] Northern analysis of WSX-1 receptor revealed transcripts in all tissues examined, with increased levels of expression in human spleen, thymus, lymph node, bone marrow, and peripheral blood leukocytes. Also, expression levels of WSX-1 increased upon activation of T-cells.

[0237] Expression of OSMR is reported to be very broad (Mosley et al, JBC 271:32635-32643, 1996). This distribution of zcytor17, WSX-1, and OSMRbeta receptors supports a role for zcytor17lig in immune responses, especially expansion of T-cells upon activation or a role in the monocyte/macrophage arm of the immune system.

[0238] Thus, particular embodiments of the present invention are directed toward use of a soluble multimeric cytokine receptor, for instance zcytor17/WSX-1/OSMR, and zcytor17/OSMR heterodimers, as antagonists in inflammatory and immune diseases or conditions such as pancreatitis, type I diabetes (IDDM), pancreatic cancer, pancreatitis, Graves Disease, inflammatory bowel disease (IBD), Crohn's Disease, colon and intestinal cancer, diverticulosis, autoimmune disease, sepsis, organ or bone marrow transplant; inflammation due to trauma, surgery or infection; amyloidosis; splenomegaly; graft versus host disease; and where inhibition of inflammation, immune suppression, reduction of proliferation of hematopoietic, immune, inflammatory or lymphoid cells, macrophages, T-cells (including Th1 and Th2 cells, CD4+ and CD8+ cells), suppression of immune response to a pathogen or antigen. Moreover the presence of zcytor17 expression in activated immune cells such as activated CD4+ and CD19+ cells showed that zcytor17 receptor may be involved in the body's immune defensive reactions against foreign invaders: such as microorganisms and cell debris, and could play a role in immune responses during inflammation and cancer formation. As such, antibodies and binding partners of the present invention that are agonistic or antagonistic to zcytor17 receptor function, such as a soluble zcytor17 multimeric cytokine receptor, can be used to modify immune response and inflammation.

[0239] The zcytor17lig structure and tissue expression suggests a role in early hematopoietic or thymocyte development and immune response regulation or inflammation. These processes involve stimulation of cell proliferation and differentiation in response to the binding of one or more cytokines to their cognate receptors. In view of the tissue distribution observed for this zcytor17lig, agonists (including the natural receptor(s)) and antagonists have enormous potential in both in vitro and in vivo applications. Compounds identified as zcytor17lig agonists are useful for stimulating proliferation and development of target cells in vitro and in vivo. For example, agonist compounds, zcytor17lig, or anti-zcytor17lig antibodies, are useful as components of defined cell culture media, and may be used alone or in combination with other cytokines and hormones to replace serum that is commonly used in cell culture. Agonists are thus useful in specifically promoting the growth and/or development or activation of monocytes, T-cells, B-cells, and other cells of the lymphoid and myeloid lineages, and hematopoietic cells in culture.

[0240] The molecules of the present invention have particular use in the monocyte/macrophage arm of the immune system. Methods are known that can assess such activity. For example, interferon gamma (IFNγ) is a potent activator of mononuclear phagocytes. For example, an increase in expression of zcytor17 upon activation of THP-1 cells (ATCC No. TIB-202) with interferon gamma could suggest that this receptor is involved in monocyte activation. Monocytes are incompletely differentiated cells that migrate to various tissues where they mature and become macrophages. Macrophages play a central role in the immune response by presenting antigen to lymphocytes and play a supportive role as accessory cells to lymphocytes by secreting numerous cytokines. Macrophages can internalize extracellular molecules and upon activation have an increased ability to kill intracellular microorganisms and tumor cells. Activated macrophages are also involved in stimulating acute or local inflammation. Moreover, monocyte-macrophage function has been shown to be abnormal in a variety of diseased states. For example see, Johnston, R B, New Eng. J. Med. 318:747-752, 1998.

[0241] One of skill in the art would recognize that agonists of zcytor17 multimeric cytokine receptor, such as zcytor17lig, are useful. For example, depressed migration of monocytes has been reported in populations with a predisposition to infection, such as newborn infants, patients receiving corticosteroid or other immunosuppressive therapy, and patients with diabetes mellitus, burns, or AIDS. Agonists for zcytor17 multimeric cytokine receptor, such as zcytor17lig, could result in an increase in the ability of monocytes to migrate and possibly prevent infection in these populations. There is also a profound defect of phagocytic killing by mononuclear phagocytes from patients with chronic granulomatous disease. This results in the formation of subcutaneous abscesses, as well as abscesses in the liver, lungs, spleen, and lymph nodes. An agonist of zcytor17 multimeric cytokine receptor, such as zcytor17lig, could correct or improve this phagocytic defect. In addition, defective monocyte cytotoxicity has been reported in patients with cancer and Wiskott-Aldrich syndrome (eczema, thrombocytopenia, and recurrent infections). Activation of monocytes by agonists of zcytor17 multimeric cytokine receptor, such as zcytor17lig, could aid in treatment of these conditions. The monocyte-macrophage system is prominently involved in several lipid-storage diseases (sphingolipidoses) such as Gaucher's disease. Resistance to infection can be impaired because of a defect in macrophage function, which could be treated by agonists to zcytor17 multimeric cytokine receptor such as zcytor17lig.

[0242] Moreover, one of skill in the art would recognize that antagonists of a zcytor17 multimeric cytokine receptor are useful. For example, in atherosclerotic lesions, one of the first abnormalities is localization of monocyte/macrophages to endothelial cells. These lesions could be prevented by use of antagonists to zcytor17lig. Zcytor17 soluble multimeric cytokine receptors, such as, for instance, heterodimers and trimers, can also be used as antagonists to the zcytor17lig. Moreover, monoblastic leukemia is associated with a variety of clinical abnormalities that reflect the release of the biologic products of the macrophage, examples include high levels of lysozyme in the serum and urine and high fevers. Moreover, such leukemias exhibit an abnormal increase of monocytic cells. These effects could possibly be prevented by antagonists to zcytor17lig, such as described herein.

[0243] Using methods known in the art, and disclosed herein, one of skill could readily assess the activity of a zcytor17 multimeric cytokine receptor in the disease states disclosed herein, inflammation, cancer, or infection as well as other disease states involving monocytic cells. In addition, as zcytor17lig is expressed in a T-cell, macrophage and monocyte-specific manner, and these diseases involve abnormalities in monocytic cells, such as cell proliferation, function, localization, and activation, the polynucleotides, polypeptides, and antibodies of the present invention can be used to as diagnostics to detect such monocytic cell abnormalities, and indicate the presence of disease. Such methods involve taking a biological sample from a patient, such as blood, saliva, or biopsy, and comparing it to a normal control sample. Histological, cytological, flow cytometric, biochemical and other methods can be used to determine the relative levels or localization of zcytor17lig, or cells expressing zcytor17lig, i.e., monocytes, in the patient sample compared to the normal control. A change in the level (increase or decrease) of zcytor17lig expression, or a change in number or localization of monocytes (e.g., increase or infiltration of monocytic cells in tissues where they are not normally present) compared to a control would be indicative of disease. Such diagnostic methods can also include using radiometric, fluorescent, and colorimetric tags attached to polynucleotides, polypeptides or antibodies of the present invention. Such methods are well known in the art and disclosed herein.

[0244] Amino acid sequences having zcytor17lig activity can be used to modulate the immune system by binding soluble zcytor17 multimeric cytokine receptor, and thus, preventing the binding of zcytor17lig with endogenous zcytor17lig receptor. Zcytor17lig antagonists, such as a zcytor17 multimeric cytokine receptor, can also be used to modulate the immune system by inhibiting the binding of Zcytor17 ligand with the endogenous zcytor17lig receptor. Accordingly, the present invention includes the use of a multimeric cytokine receptor that can be also used to treat a subject which produces an excess of either zcytor17lig or Zcytor17 comprising receptor(s). Suitable subjects include mammals, such as humans or veterinary animals.

[0245] Zcytor17lig has been shown to be expressed in activated mononuclear cells, and may be involved in regulating inflammation. As such, polypeptides of the present invention can be assayed and used for their ability to modify inflammation, or can be used as a marker for inflammation. Methods to determine proinflammatory and antiinflammatory qualities of zcytor17lig are known in the art and discussed herein. Moreover, it may be involved in up-regulating the production of acute phase reactants, such as serum amyloid A (SAA), α1-antichymotrypsin, and haptoglobin, and that expression of zcytor17 receptor ligand may be increased upon injection of lipopolysaccharide (LPS) in vivo that are involved in inflammatory response (Dumoutier, L. et al., Proc. Nat'l. Acad. Sci. 97:10144-10149 (2000)). Production of acute phase proteins, such as SAA, is considered a short-term survival mechanism where inflammation is beneficial; however, maintenance of acute phase proteins for longer periods contributes to chronic inflammation and can be harmful to human health. For review, see Uhlar, C M and Whitehead, A S, Eur. J. Biochem. 265:501-523 (1999); and Baumann H. and Gauldie, J. Immunology Today 15:74-80 (1994). Moreover, the acute phase protein SAA is implicated in the pathogenesis of several chronic inflammatory diseases, is implicated in atherosclerosis and rheumatoid arthritis, and is the precursor to the amyloid A protein deposited in amyloidosis (Uhlar, C M and Whitehead, supra.). Thus, where a ligand such as zcytor17lig that acts as a pro-inflammatory molecule and induces production of SAA, antagonists would be useful in treating inflammatory disease and other diseases associated with acute phase response proteins induced by the ligand. Such antagonists are provided by the present invention. For example, a method of reducing inflammation comprises administering to a mammal with or at risk of developing inflammation an amount of a composition of a soluble multimeric cytokine receptor that is sufficient to reduce inflammation. Moreover, a method of suppressing an inflammatory response in a mammal with inflammation can comprise: (1) determining a level of serum amyloid A protein; (2) administering a composition comprising a soluble multimeric cytokine receptor polypeptide as described herein in an acceptable pharmaceutical vehicle; (3) determining a post administration level of serum amyloid A protein; (4) comparing the level of serum amyloid A protein in step (1) to the level of serum amyloid A protein in step (3), wherein a lack of increase or a decrease in serum amyloid A protein level is indicative of suppressing an inflammatory response.

[0246] Like zcytor17lig, analysis of the tissue distribution of the mRNA corresponding it's zcytor17 receptor cDNA showed that mRNA level was highest in monocytes and prostate cells, and is elevated in activated monocytes, and activated CD4+, activated CD8+, and activated CD3+ cells. Hence, zcytor17 receptor is also implicated in inducing inflammatory and immune response. Thus, particular embodiments of the present invention are directed toward use of zcytor17lig-antibodies, and zcytor17lig, as well as soluble zcytor17 receptor heterodimers as antagonists in inflammatory and immune diseases or conditions such as pancreatitis, type I diabetes (IDDM), pancreatic cancer, pancreatitis, Graves Disease, inflammatory bowel disease (IBD), Crohn's Disease, colon and intestinal cancer, diverticulosis, autoimmune disease, sepsis, organ or bone marrow transplant; inflammation due to trauma, sugery or infection; amyloidosis; splenomegaly; graft versus host disease; and where inhibition of inflammation, immune suppression, reduction of proliferation of hematopoietic, immune, inflammatory or lymphoid cells, macrophages, T-cells (including Th1 and Th2 cells, CD4+ and CD8+ cells), suppression of immune response to a pathogen or antigen. Moreover the presence of zcytor17 receptor and zcytor17lig expression in activated immune cells such as activated CD3+, monocytes, CD4+ and CD19+ cells showed that zcytor17 receptor may be involved in the body's immune defensive reactions against foreign invaders: such as microorganisms and cell debris, and could play a role in immune responses during inflammation and cancer formation. As such, zcytor17lig and zcytor17lig-antibodies of the present invention that are agonistic or antagonistic to zcytor17 receptor function, can be used to modify immune response and inflammation.

[0247] Moreover, zcytor17lig polypeptides that bind zcytor17 multimeric cytokine receptors and antibodies thereto are useful to:

[0248] 1) Antagonize or block signaling via a zcytor17 multimeric cytokine receptor in the treatment of acute inflammation, inflammation as a result of trauma, tissue injury, surgery, sepsis or infection, and chronic inflammatory diseases such as asthma, inflammatory bowel disease (IBD), chronic colitis, splenomegaly, rheumatoid arthritis, recurrent acute inflammatory episodes (e.g., tuberculosis), and treatment of amyloidosis, and atherosclerosis, Castleman's Disease, asthma, and other diseases associated with the induction of acute-phase response.

[0249] 2) Antagonize or block signaling via the zcytor17 multimeric cytokine receptor in the treatment of autoimmune diseases such as IDDM, multiple sclerosis (MS), systemic Lupus erythematosus (SLE), myasthenia gravis, rheumatoid arthritis, and IBD to prevent or inhibit signaling in immune cells (e.g. lymphocytes, monocytes, leukocytes) via zcytor17 receptor (Hughes C et al., J. Immunol 153: 3319-3325 (1994)). Asthma, allergy and other atopic disease may be treated with an MAb against, for example, soluble zcytor17 multimeric cytokine receptors or zcytor17/CRF2-4 heterodimers, to inhibit the immune response or to deplete offending cells. Blocking or inhibiting signaling via zcytor17 multimeric cytokine receptor, using the polypeptides and antibodies of the present invention, may also benefit diseases of the pancreas, kidney, pituitary and neuronal cells. IDDM, NIDDM, pancreatitis, and pancreatic carcinoma may benefit. Zcytor17 multimeric cytokine receptor may serve as a target for MAb therapy of cancer where an antagonizing MAb inhibits cancer growth and targets immune-mediated killing. (Holliger P, and Hoogenboom, H Nature Biotech. 16: 1015-1016 (1998)). Mabs to soluble zcytor17 receptor monomers, homodimers, heterodimers and multimers may also be useful to treat nephropathies such as glomerulosclerosis, membranous neuropathy, amyloidosis (which also affects the kidney among other tissues), renal arteriosclerosis, glomerulonephritis of various origins, fibroproliferative diseases of the kidney, as well as kidney dysfunction associated with SLE, IDDM, type II diabetes (NIDDM), renal tumors and other diseases.

[0250] 3) Agonize or initiate signaling via the zcytor17 multimeric cytokine receptor in the treatment of autoimmune diseases such as IDDM, MS, SLE, myasthenia gravis, rheumatoid arthritis, and IBD. Zcytor17lig may signal lymphocytes or other immune cells to differentiate, alter proliferation, or change production of cytokines or cell surface proteins that ameliorate autoimmunity. Specifically, modulation of a T-helper cell response to an alternate pattern of cytokine secretion may deviate an autoimmune response to ameliorate disease (Smith J A et al., J. Immunol. 160:4841-4849 (1998)). Similarly, zcytor17lig may be used to signal, deplete and deviate immune cells involved in asthma, allergy and atopoic disease. Signaling via zcytor17 multimeric cytokine receptor may also benefit diseases of the pancreas, kidney, pituitary and neuronal cells. IDDM, NIDDM, pancreatitis, and pancreatic carcinoma may benefit. Zcytor17 multimeric cytokine receptor may serve as a target for MAb therapy of pancreatic cancer where a signaling MAb inhibits cancer growth and targets immune-mediated killing (Tutt, A L et al., J Immunol. 161: 3175-3185 (1998)). Similarly T-cell specific leukemias, lymphomas, plasma cell dyscrasia (e.g., multiple myeloma), and carcinoma may be treated with monoclonal antibodies (e.g., neutralizing antibody) to zcytor17-comprising soluble receptors of the present invention.

[0251] Soluble zcytor17 multimeric cytokine receptors as described herein can be used to neutralize/block zcytor17 receptor ligand activity in the treatment of autoimmune disease, atopic disease, NIDDM, pancreatitis and kidney dysfunction as described above. A soluble form of zcytor17 multimeric cytokine receptor may be used to promote an antibody response mediated by T cells and/or to promote the production of IL-4 or other cytokines by lymphocytes or other immune cells.

[0252] A soluble zcytor17 multimeric cytokine receptor may be useful as antagonists of zcytor17lig. Such antagonistic effects can be achieved by direct neutralization or binding of its natural ligand. In addition to antagonistic uses, the soluble receptors can bind zcytor17lig and act as carrier or vehicle proteins, in order to transport zcytor17lig to different tissues, organs, and cells within the body. As such, the soluble receptors can be fused or coupled to molecules, polypeptides or chemical moieties that direct the soluble-receptor-ligand complex to a specific site, such as a tissue, specific immune cell, monocytes, or tumor. For example, in acute infection or some cancers, benefit may result from induction of inflammation and local acute phase response proteins. Thus, the soluble receptors described herein or antibodies thereto can be used to specifically direct the action of a pro-inflammatory zcytor17lig ligand. See, Cosman, D. Cytokine 5: 95-106 (1993); and Fernandez-Botran, R. Exp. Opin. Invest. Drugs 9:497-513 (2000).

[0253] Moreover, the soluble zcytor17 multimeric cytokine receptors can be used to stabilize the zcytor17lig, to increase the bioavailability, therapeutic longevity, and/or efficacy of the ligand by stabilizing the ligand from degradation or clearance, or by targeting the ligand to a site of action within the body. For example, the naturally occurring IL-6/soluble IL-6R complex stabilizes IL-6 and can signal through the gp130 receptor. See, Cosman, D. supra., and Fernandez-Botran, R. supra. Moreover, Zcytor17 may be combined with a cognate ligand such as its ligand to comprise a ligand/soluble receptor complex. Such complexes may be used to stimulate responses from cells presenting a companion receptor subunit. The cell specificity of zcytor17 multimeric cytokine receptor/zcytor17lig complexes may differ from that seen for the ligand administered alone. Furthermore the complexes may have distinct pharmacokinetic properties such as affecting half-life, dose/response and organ or tissue specificity. Zcytor17 multimeric cytokine receptor/ligand complexes thus may have agonist activity to enhance an immune response or stimulate mesangial cells or to stimulate hepatic cells. Alternatively, only tissues expressing a signaling subunit the heterodimerizes with the complex may be affected analogous to the response to IL6/IL6R complexes (Hirota H. et al., Proc. Nat'l. Acad. Sci. 92:4862-4866 (1995); and Hirano, T. in Thomason, A. (Ed.) “The Cytokine Handbook”, 3^(rd) Ed., p. 208-209). Soluble receptor/cytokine complexes for IL12 and CNTF display similar activities.

[0254] Zcytor17lig may also be used within diagnostic systems for the detection of circulating levels of ligand, and in the detection of acute phase inflammatory response. Within a related embodiment, antibodies or other agents that specifically bind to zcytor17lig can be used to detect circulating zcytor17lig polypeptides; conversely, zcytor17lig itself can be used to detect circulating or locally-acting receptor polypeptides. Elevated or depressed levels of ligand or receptor polypeptides may be indicative of pathological conditions, including inflammation or cancer. Moreover, detection of acute phase proteins or molecules such as zcytor17lig can be indicative of a chronic inflammatory condition in certain disease states (e.g., rheumatoid arthritis). Detection of such conditions serves to aid in disease diagnosis as well as help a physician in choosing proper therapy.

[0255] Polynucleotides encoding a zcytor17 multimeric cytokine receptor are useful within gene therapy applications where it is desired to increase or inhibit zcytor17lig activity. If a mammal has a mutated or absent zcytor17 gene, the zcytor17 gene of the present invention can be introduced into the cells of the mammal. In one embodiment, a gene encoding a zcytor17 multimeric cytokine receptor is introduced in vivo in a viral vector. Such vectors include an attenuated or defective DNA virus, such as, but not limited to, herpes simplex virus (HSV), papillomavirus, Epstein Barr virus (EBV), adenovirus, adeno-associated virus (AAV), and the like. Defective viruses, which entirely or almost entirely lack viral genes, are preferred. A defective virus is not infective after introduction into a cell. Use of defective viral vectors allows for administration to cells in a specific, localized area, without concern that the vector can infect other cells. Examples of particular vectors include, but are not limited to, a defective herpes simplex virus 1 (HSV1) vector (Kaplitt et al., Molec. Cell. Neurosci. 2:320-30 (1991)); an attenuated adenovirus vector, such as the vector described by Stratford-Perricaudet et al., J. Clin. Invest. 90:626-30 (1992); and a defective adeno-associated virus vector (Samulski et al., J. Virol. 61:3096-101 (1987); and Samulski et al., J. Virol. 63:3822-8 (1989)).

[0256] A zcytor17 gene of the present invention can be introduced in a retroviral vector, e.g., as described in Anderson et al., U.S. Pat. No. 5,399,346; Mann et al. Cell 33:153 (1983); Temin et al., U.S. Pat. No. 4,650,764; Temin et al., U.S. Pat. No. 4,980,289; Markowitz et al., J. Virol. 62:1120 (1988); Temin et al., U.S. Pat. No. 5,124,263; International Patent Publication No. WO 95/07358, published Mar. 16, 1995 by Dougherty et al.; and Kuo et al., Blood 82:845 (1993). Alternatively, the vector can be introduced by lipofection in vivo using liposomes. Synthetic cationic lipids can be used to prepare liposomes for in vivo transfection of a gene encoding a marker (Felgner et al., Proc. Natl. Acad. Sci. USA 84:7413-7 (1987); Mackey et al., Proc. Natl. Acad. Sci. USA 85:8027-31 (1988)). The use of lipofection to introduce exogenous genes into specific organs in vivo has certain practical advantages. Molecular targeting of liposomes to specific cells represents one area of benefit. More particularly, directing transfection to particular cells represents one area of benefit. For instance, directing transfection to particular cell types would be particularly advantageous in a tissue with cellular heterogeneity, such as the immune system, pancreas, liver, kidney, and brain. Lipids may be chemically coupled to other molecules for the purpose of targeting. Targeted peptides (e.g., hormones or neurotransmitters), proteins such as antibodies, or nori-peptide molecules can be coupled to liposomes chemically.

[0257] It is possible to remove the target cells from the body; to introduce the vector as a naked DNA plasmid; and then to re-implant the transformed cells into the body. Naked DNA vectors for gene therapy can be introduced into the desired host cells by methods known in the art, e.g., transfection, electroporation, microinjection, transduction, cell fusion, DEAE dextran, calcium phosphate precipitation, use of a gene gun or use of a DNA vector transporter. See, e.g., Wu et al., J. Biol. Chem. 267:963-7 (1992); and Wu et al., J. Biol. Chem. 263:14621-4 (1988).

[0258] Antisense methodology can be used to inhibit zcytor17 multimeric cytokine receptor gene transcription, such as to inhibit cell proliferation in vivo. Polynucleotides that are complementary to a segment of a zcytor17-encoding polynucleotide (e.g., a polynucleotide as set forth in SEQ ID NO: 110. SEQ ID NO: 108, or SEQ ID NO: 4) are designed to bind to zcytor17lig-encoding mRNA and to inhibit translation of such mRNA. Such antisense polynucleotides are used to inhibit expression of zcytor17lig polypeptide-encoding genes in cell culture or in a subject.

[0259] Mice engineered to express the zcytor17lig gene, referred to as “transgenic mice,” and mice that exhibit a complete absence of zcytor17lig gene function, referred to as “knockout mice,” may also be generated (Snouwaert et al., Science 257:1083 (1992); Lowell et al., Nature 366:740-42 (1993); Capecchi, M. R., Science 244: 1288-1292 (1989); Palmiter, R. D. et al. Annu Rev Genet. 20: 465-499 (1986)). For example, transgenic mice that over-express zcytor17lig, either ubiquitously or under a tissue-specific or tissue-restricted promoter can be used to ask whether over-expression causes a phenotype. For example, over-expression of a wild-type zcytor17lig polypeptide, polypeptide fragment or a mutant thereof may alter normal cellular processes, resulting in a phenotype that identifies a tissue in which zcytor17lig expression is functionally relevant and may indicate a therapeutic target for the zcytor17lig, its agonists or antagonists. For example, a preferred transgenic mouse to engineer is one that over-expresses the zcytor17lig (amino acid residues 23-164 of SEQ ID NO: 2; or 24-163 of SEQ ID NO: 11). Moreover, such over-expression may result in a phenotype that shows similarity with human diseases. Similarly, knockout zcytor17lig mice can be used to determine where zcytor17lig is absolutely required in vivo. The phenotype of knockout mice is predictive of the in vivo effects of that a zcytor17lig antagonist, such as a soluble zcytor17 multimeric cytokine receptor, may have. The human or mouse zcytor17lig cDNA described herein can be used to generate knockout mice. These mice may be employed to study the zcytor17lig gene and the protein encoded thereby in an in vivo system, and can be used as in vivo models for corresponding human diseases. Moreover, transgenic mice expression of zcytor17lig antisense polynucleotides or ribozymes directed against zcytor17lig, described herein, can be used analogously to transgenic mice described above. Studies may be carried out by administration of purified zcytor17lig protein, as well.

[0260] The present invention also provides a composition which includes an effective amount of a soluble multimeric cytokine receptor comprising a polypeptide comprising amino acid residue 20 to amino acid residue 543 of SEQ ID NO: 111 and at least a portion of at least one class I cytokine receptor; and a pharmaceutically acceptable vehicle. The polypeptide may be comprised of various fragement or portions of the extracellular domain of SEQ ID NO: 111, SEQ ID NO: 109, and/or SEQ ID NO: 5, such as for instance, amino acid residue 20 to amino acid residue 227 of SEQ ID NO: 111 and amino acid residue 20 to amino acid residue 519 of SEQ ID NO: 111. The at least a portion of at least one class I cytokine receptor can include, for example, a portion of SEQ ID NO: 9 and/or a portion of SEQ ID NO: 7, such as, for instance, amino acid residue 28 to amino acid residue 429 of SEQ ID NO: 7, amino acid residue 35 to amino acid residue 137 of SEQ ID NO: 7, amino acid residue 240 to amino acid residue 342 of SEQ ID NO: 7, amino acid residue 348 to amino acid residue 429 of SEQ ID NO: 7, amino acid residue 28 to amino acid residue 739 of SEQ ID NO: 7, and/or combinations thereof. The multimeric cytokine receptor may further include an affinity tag as described herein.

[0261] The present invention also provides an immune cell inhibiting composition which includes an effective amount of a soluble multimeric cytokine receptor comprising a polypeptide comprising amino acid residue 20 to amino acid residue 227 of SEQ ID NO: 111 and at least a portion of at least one class I cytokine receptor; and a pharmaceutically acceptable vehicle, wherein the soluble multimeric cytokine receptor inhibits the proliferation of immune cells.

[0262] The present invention also provides an inflammatory cell inhibiting composition which includes an effective amount of a soluble multimeric cytokine receptor comprising a polypeptide comprising amino acid residue 20 to amino acid residue 227 of SEQ ID NO: 111 and at least a portion of at least one class I cytokine receptor; and a pharmaceutically acceptable vehicle, wherein the soluble multimeric cytokine receptor inhibits the proliferation of inflammatory cells.

[0263] Experimental evidence suggests a role for zcytor17lig in the progression of diseases that involve the skin or epithelium of internal surfaces, such as, for instance, large intestine, small intestine, pancrease, lung, prostate, uterus, and the like. First, as disclosed herein, zcytor17 receptors, including both OSM receptor beta and zcytor17, are expressed in several cell types located in epithelial surfaces including cell lines derived from lung epithelium, lung fibroblast, prostate, colon, breast, liver epithelium, bone and skin epithelium, bone fibroblast, and the like. Moreover, as disclosed herein, examples from each of these cell types also responded to zcytor17lig activation of a STAT reporter construct. In addition, several cell lines responded to zcytor17lig stimulation by producing increased levels of IL-6, IL-8, MCP-1 (a chemotactic factor) as described herein. In whole, these data suggest a role for zcytor17lig in diseases that involve the epithelium such as, for instance, atopic dermatitis; dermatitis; psoriasis; psoriatic arthritis; eczema; gingivitis; peridontal disease; inflammatory bowel diseases (IBD) (e.g., ulcerative colitis, Crohn's disease); reproductive disorders, such as, for instance, cervical dysplasia, cervical cancer; other skin diseases like cancers: sarcomas; canrcinomas; melanoma, etc. i.e, not just inflammatory diseases, since immune system is involved in activating/curing cancers; diseases involving barrier dysfunction, such as, for instance, graft-versus-host disease (GVHD) and irritable bowel syndrome (IBS); and diseases that involve lung epithelium, such as asthma, emphysema, and the like. In addition, the release of cytokines IL-6, IL-8, and MCP-1 by cells exposed to zcytor17lig suggests that zcytor17lig is involved in inflammation. Therefore, regulation of zcytor17lig can be useful in the treatment of autoimmune, inflammatory, or cancerous diseases associated with the tissues that express receptor. These diseases include, for example, prostatitis, hepatitis, osteoarthritis, and the like. Zcytor17lig may positively or negatively directly or indirectly regulate these diseases. Therefore, the administration of zcytor17lig can be used to treat diseases as described herein directly or with molecules that inhibit zcytor17lig activity including, for example, both monoclonal antibodies to zcytor17lig or monoclonal antibodies to zcytor17, or monoclonal antibodies that recognize the zcytor17 and OSM receptor beta complex.

[0264] Data also suggests that zcytor17lig may be involved in the regulation of TH2 T cell mediated diseases. First, zcytor17lig is made by the TH2 subset of activated T cells. TH2 cells express more zcytor17lig as compared to TH1 cells. In addition, at least two lung epithelial cell lines (SK-LU-1, A549) were stimulated to increase IL13 receptor alpha-2 mRNA in response to zcyto17 ligand stimulation as described herein. There is an association of IL-13 receptor alpha2 chain and tumorigenicity of human breast and pancreatic tumors. This suggests that zcytor17lig may play a role in regulating tumorigenicity of these types of cancers, as well as other cancers. Therefore, the administration of a zcytor17lig antagonist or direct use of zcytor17lig may be useful in treatment of these types of cancers, benign or malignant and at various grades (grades I-IV) and stages (e.g., TNM or AJC staging methods) of tumor development, in mammals, preferably humans.

[0265] It is well-known in the art that IL13 is involved in the generation of activated TH2 cells and in TH2 mediated diseases, such as asthma, atopic dermatitis, and the like. Zcytor17lig or zcytor17lig antagonists may be useful in the treatment of diseases that involved TH2 T cells. This would include diseases such as, for instance, atopic dermatitis, asthma, as well as other diseases that are exacerbated by activated TH2 cells. The involvement of zcytor17lig in diseases, such as, for instance, atopic dermatitis, is also supported by the phenotype of the transgenic mice that overexpress zcytor17lig and develop symptoms of atopic dermatitis as described herein.

[0266] Despite the preferential expression of zcytor17lig by TH2 cells, there is still some expression of zcytor17lig in TH1 cells and in CD8+ T cells. Therefore, zcytor17lig or its antagonists may be useful in treating diseases that involve immune modulation of activated T cells including, for example, viral infection, cancers, graft rejection, and the like.

[0267] Zcytor17lig may also be involved in the development of cancer. There is expression of the zcytor17 and OSM receptor beta receptors in human bone fibroblast osteosarcomas, human skin fibroblast melanoma, colon epithelial carcinoma, adenocarcinoma, breast epithelial adenocarcinoma, prostate epithelial adenosarcoma, and lung epithelial adenocarcinoma and carcinoma. Therefore, it may be useful to treat tumors of epithelial origin with either zcytor17lig, fragments thereof, or zcytor17lig antagonists which include, but are not limited to, carcinoma, adenocarcinoma, and melanoma. Notwithstanding, zcytor17lig or a zcytor17lig antagonist may be used to treat a cancer, or reduce one or more symptoms of a cancer, from a cancer including but not limited to, squamous cell or epidermoid carcinoma, basal cell carcinoma, adenocarcinoma, papillary carcinoma, cystadenocarcinoma, bronchogenic carcinoma, bronchial adenoma, melanoma, renal cell carcinoma, hepatocellular carcinoma, transitional cell carcinoma, choriocarcinoma, seminoma, embryonal carcinoma, malignant mixed tumor of salivary gland origin, Wilms' tumor, immature teratoma, teratocarcinoma, and other tumors comprising at least some cells of epithelial origin.

[0268] Generally, the dosage of administered zcytor17lig polypeptide (or Zcytor16 analog or fusion protein) will vary depending upon such factors as the patient's age, weight, height, sex, general medical condition and previous medical history. Typically, it is desirable to provide the recipient with a dosage of zcytor17lig polypeptide which is in the range of from about 1 pg/kg to 10 mg/kg (amount of agent/body weight of patient), although a lower or higher dosage also may be administered as circumstances dictate. One skilled in the art can readily determine such dosages, and adjustments thereto, using methods known in the art.

[0269] Administration of a zcytor17 multimeric receptor agonist or antagonist to a subject can be topical, inhalant, intravenous, intraarterial, intraperitoneal, intramuscular, subcutaneous, intrapleural, intrathecal, by perfusion through a regional catheter, or by direct intralesional injection. When administering therapeutic proteins by injection, the administration may be by continuous infusion or by single or multiple boluses.

[0270] Additional routes of administration include oral, mucosal-membrane, pulmonary, and transcutaneous. Oral delivery is suitable for polyester microspheres, zein microspheres, proteinoid microspheres, polycyanoacrylate microspheres, and lipid-based systems (see, for example, DiBase and Morrel, “Oral Delivery of Microencapsulated Proteins,” in Protein Delivery: Physical Systems, Sanders and Hendren (eds.), pages 255-288 (Plenum Press 1997)). The feasibility of an intranasal delivery is exemplified by such a mode of insulin administration (see, for example, Hinchcliffe and Illum, Adv. Drug Deliv. Rev. 35:199 (1999)). Dry or liquid particles comprising Zcytor17 multimeric receptor agonist or antagonist can be prepared and inhaled with the aid of dry-powder dispersers, liquid aerosol generators, or nebulizers (e.g., Pettit and Gombotz, TIBTECH 16:343 (1998); Patton et al., Adv. Drug Deliv. Rev. 35:235 (1999)). This approach is illustrated by the AERX diabetes management system, which is a hand-held electronic inhaler that delivers aerosolized insulin into the lungs. Studies have shown that proteins as large as 48,000 kDa have been delivered across skin at therapeutic concentrations with the aid of low-frequency ultrasound, which illustrates the feasibility of trascutaneous administration (Mitragotri et al., Science 269:850 (1995)). Transdermal delivery using electroporation provides another means to administer a molecule having Zcytor17 multimeric receptor binding activity (Potts et al., Pharm. Biotechnol. 10:213 (1997)).

[0271] A pharmaceutical composition comprising a protein, polypeptide, or peptide having Zcytor17 multimeric receptor binding activity can be formulated according to known methods to prepare pharmaceutically useful compositions, whereby the therapeutic proteins are combined in a mixture with a pharmaceutically acceptable vehicle. A composition is said to be in a “pharmaceutically acceptable vehicle” if its administration can be tolerated by a recipient patient. Sterile phosphate-buffered saline is one example of a pharmaceutically acceptable vehicle. Other suitable vehicles are well-known to those in the art. See, for example, Gennaro (ed.), Remington's Pharmaceutical Sciences, 19th Edition (Mack Publishing Company 1995).

[0272] For purposes of therapy, molecules having Zcytor17 multimeric receptor binding activity and a pharmaceutically acceptable vehicle are administered to a patient in a therapeutically effective amount. A combination of a protein, polypeptide, or peptide having Zcytor17 multimeric receptor binding activity and a pharmaceutically acceptable vehicle is said to be administered in a “therapeutically effective amount” or “effective amount” if the amount administered is physiologically significant. An agent is physiologically significant if its presence results in a detectable change in the physiology of a recipient patient. For example, an agent used to treat inflammation is physiologically significant if its presence alleviates at least a portion of the inflammatory response.

[0273] A pharmaceutical composition comprising Zcytor17lig (or Zcytor17lig analog or fusion protein) can be furnished in liquid form, in an aerosol, or in solid form. Liquid forms, are illustrated by injectable solutions, aerosols, droplets, topological solutions and oral suspensions. Exemplary solid forms include capsules, tablets, and controlled-release forms. The latter form is illustrated by miniosmotic pumps and implants (Bremer et al., Pharm. Biotechnol. 10:239 (1997); Ranade, “Implants in Drug Delivery,” in Drug Delivery Systems, Ranade and Hollinger (eds.), pages 95-123 (CRC Press 1995); Bremer et al., “Protein Delivery with Infusion Pumps,” in Protein Delivery: Physical Systems, Sanders and Hendren (eds.), pages 239-254 (Plenum Press 1997); Yewey et al., “Delivery of Proteins from a Controlled Release Injectable Implant,” in Protein Delivery: Physical Systems, Sanders and Hendren (eds.), pages 93-117 (Plenum Press 1997)). Other solid forms include creams, pastes, other topological applications, and the like.

[0274] Liposomes provide one means to deliver therapeutic polypeptides to a subject intravenously, intraperitoneally, intrathecally, intramuscularly, subcutaneously, or via oral administration, inhalation, or intranasal administration. Liposomes are microscopic vesicles that consist of one or more lipid bilayers surrounding aqueous compartments (see, generally, Bakker-Woudenberg et al., Eur. J. Clin. Microbiol. Infect. Dis. 12 (Suppl. 1):S61 (1993), Kim, Drugs 46:618 (1993), and Ranade, “Site-Specific Drug Delivery Using Liposomes as Carriers,” in Drug Delivery Systems, Ranade and Hollinger (eds.), pages 3-24 (CRC Press 1995)). Liposomes are similar in composition to cellular membranes and as a result, liposomes can be administered safely and are biodegradable. Depending on the method of preparation, liposomes may be unilamellar or multilamellar, and liposomes can vary in size with diameters ranging from 0.02 μm to greater than 10 μm. A variety of agents can be encapsulated in liposomes: hydrophobic agents partition in the bilayers and hydrophilic agents partition within the inner aqueous space(s) (see, for example, Machy et al., Liposomes In Cell Biology And Pharmacology (John Libbey 1987), and Ostro et al., American J. Hosp. Pharm. 46:1576 (1989)). Moreover, it is possible to control the therapeutic availability of the encapsulated agent by varying liposome size, the number of bilayers, lipid composition, as well as the charge and surface characteristics of the liposomes.

[0275] Liposomes can adsorb to virtually any type of cell and then slowly release the encapsulated agent. Alternatively, an absorbed liposome may be endocytosed by cells that are phagocytic. Endocytosis is followed by intralysosomal degradation of liposomal lipids and release of the encapsulated agents (Scherphof et al., Ann. N.Y. Acad. Sci. 446:368 (1985)). After intravenous administration, small liposomes (0.1 to 1.0 μm) are typically taken up by cells of the reticuloendothelial system, located principally in the liver and spleen, whereas liposomes larger than 3.0 μm are deposited in the lung. This preferential uptake of smaller liposomes by the cells of the reticuloendothelial system has been used to deliver chemotherapeutic agents to macrophages and to tumors of the liver.

[0276] The reticuloendothelial system can be circumvented by several methods including saturation with large doses of liposome particles, or selective macrophage inactivation by pharmacological means (Claassen et al., Biochim. Biophys. Acta 802:428 (1984)). In addition, incorporation of glycolipid- or polyethelene glycol-derivatized phospholipids into liposome membranes has been shown to result in a significantly reduced uptake by the reticuloendothelial system (Allen et al., Biochim. Biophys. Acta 1068:133 (1991); Allen et al., Biochim. Biophys. Acta 1150:9 (1993)).

[0277] Liposomes can also be prepared to target particular cells or organs by varying phospholipid composition or by inserting receptors or ligands into the liposomes. For example, liposomes, prepared with a high content of a nonionic surfactant, have been used to target the liver (Hayakawa et al., Japanese Patent 04-244,018; Kato et al., Biol. Pharm. Bull. 16:960 (1993)). These formulations were prepared by mixing soybean phospatidylcholine, α-tocopherol, and ethoxylated hydrogenated castor oil (HCO-60) in methanol, concentrating the mixture under vacuum, and then reconstituting the mixture with water. A liposomal formulation of dipalmitoylphosphatidylcholine (DPPC) with a soybean-derived sterylglucoside mixture (SG) and cholesterol (Ch) has also been shown to target the liver (Shimizu et al., Biol. Pharm. Bull. 20:881 (1997)).

[0278] Alternatively, various targeting ligands can be bound to the surface of the liposome, such as antibodies, antibody fragments, carbohydrates, vitamins, and transport proteins. For example, liposomes can be modified with branched type galactosyllipid derivatives to target asialoglycoprotein (galactose) receptors, which are exclusively expressed on the surface of liver cells (Kato and Sugiyama, Crit. Rev. Ther. Drug Carrier Syst. 14:287 (1997); Murahashi et al., Biol. Pharm. Bull.20:259 (1997)). Similarly, Wu et al., Hepatology 27:772 (1998), have shown that labeling liposomes with asialofetuin led to a shortened liposome plasma half-life and greatly enhanced uptake of asialofetuin-labeled liposome by hepatocytes. On the other hand, hepatic accumulation of liposomes comprising branched type galactosyllipid derivatives can be inhibited by preinjection of asialofetuin (Murahashi et al., Biol. Pharm. Bull.20:259 (1997)). Polyaconitylated human serum albumin liposomes provide another approach for targeting liposomes to liver cells (Kamps et al., Proc. Nat'l Acad. Sci. USA 94:11681 (1997)). Moreover, Geho, et al. U.S. Pat. No. 4,603,044, describe a hepatocyte-directed liposome vesicle delivery system, which has specificity for hepatobiliary receptors associated with the specialized metabolic cells of the liver.

[0279] In a more general approach to tissue targeting, target cells are prelabeled with biotinylated antibodies specific for a ligand expressed by the target cell (Harasym et al., Adv. Drug Deliv. Rev. 32:99 (1998)). After plasma elimination of free antibody, streptavidin-conjugated liposomes are administered. In another approach, targeting antibodies are directly attached to liposomes (Harasym et al., Adv. Drug Deliv. Rev. 32:99 (1998)).

[0280] Polypeptides having Zcytor17 multimeric receptor binding activity can be encapsulated within liposomes using standard techniques of protein microencapsulation (see, for example, Anderson et al., Infect. Immun. 31:1099 (1981), Anderson et al., Cancer Res. 50:1853 (1990), and Cohen et al., Biochim. Biophys. Acta 1063:95 (1991), Alving et al. “Preparation and Use of Liposomes in Immunological Studies,” in Liposome Technology, 2nd Edition, Vol. III, Gregoriadis (ed.), page 317 (CRC Press 1993), Wassef et al., Meth. Enzymol. 149:124 (1987)). As noted above, therapeutically useful liposomes may contain a variety of components. For example, liposomes may comprise lipid derivatives of poly(ethylene glycol) (Allen et al., Biochim. Biophys. Acta 1150:9 (1993)).

[0281] Degradable polymer microspheres have been designed to maintain high systemic levels of therapeutic proteins. Microspheres are prepared from degradable polymers such as poly(lactide-co-glycolide) (PLG), polyanhydrides, poly (ortho esters), nonbiodegradable ethylvinyl acetate polymers, in which proteins are entrapped in the polymer (Gombotz and Pettit, Bioconjugate Chem. 6:332 (1995); Ranade, “Role of Polymers in Drug Delivery,” in Drug Delivery Systems, Ranade and Hollinger (eds.), pages 51-93 (CRC Press 1995); Roskos and Maskiewicz, “Degradable Controlled Release Systems Useful for Protein Delivery,” in Protein Delivery: Physical Systems, Sanders and Hendren (eds.), pages 45-92 (Plenum Press 1997); Bartus et al., Science 281:1161 (1998); Putney and Burke, Nature Biotechnology 16:153 (1998); Putney, Curr. Opin. Chem. Biol. 2:548 (1998)). Polyethylene glycol (PEG)-coated nanospheres can also provide vehicles for intravenous administration of therapeutic proteins (see, for example, Gref et al., Pharm. Biotechnol. 10:167 (1997)).

[0282] The present invention also contemplates chemically modified polypeptides having binding Zcytor17 multimeric receptor activity such as zcytor17 multimeric receptor heterodimeric or multimeric soluble receptors, and Zcytor17 multimeric receptor antagonists, for example anti-zcytor17 multimeric receptor antibodies or binding polypeptides, which a polypeptide is linked with a polymer, as discussed above.

[0283] Other dosage forms can be devised by those skilled in the art, as shown, for example, by Ansel and Popovich, Pharmaceutical Dosage Forms and Drug Delivery Systems, 5^(th) Edition (Lea & Febiger 1990), Gennaro (ed.), Remington's Pharmaceutical Sciences, 19^(th) Edition (Mack Publishing Company 1995), and by Ranade and Hollinger, Drug Delivery Systems (CRC Press 1996).

[0284] As an illustration, pharmaceutical compositions may be supplied as a kit comprising a container that comprises a polypeptide with a Zcytor17 multimeric receptor extracellular domain, e.g., zcytor17 multimeric receptor heterodimeric or multimeric soluble receptors, or a Zcytor17 multimeric receptor antagonist (e.g., a neutralizing antibody or antibody fragment that binds a Zcytor17 multimeric receptor polypeptide). Therapeutic polypeptides can be provided in the form of an injectable solution for single or multiple doses, or as a sterile powder that will be reconstituted before injection. Alternatively, such a kit can include a dry-powder disperser, liquid aerosol generator, or nebulizer for administration of a therapeutic polypeptide. Such a kit may further comprise written information on indications and usage of the pharmaceutical composition. Moreover, such information may include a statement that the Zcytor17 multimeric receptor composition is contraindicated in patients with known hypersensitivity to Zcytor17 multimeric receptor.

The foregoing detailed description and examples have been given for clarity of understanding only. No unnecessary limitations are to be understood therefrom.

EXAMPLES Example 1

[0286] Construction of MPL-zcytor17 Polypeptide Chimera: MPL Extracellular and TM

[0287] Domain Fused to the zcytor17 Intracellular Signaling Domain

[0288] The 5′ extracellular domain of the murine MPL receptor was isolated from a plasmid containing the murine MPL receptor (PHZ1/MPL plasmid) by digestion with EcoRI and BamHI generating a 1164 bp fragment. The digestion was run on a 1% agarose gel and the fragment was isolated using the Qiaquick gel extraction kit (Qiagen) as per manufacturer's instructions. The rest of the MPL extracellular domain and transmembrane domain were generated using PCR with primers ZC6,673 (SEQ ID NO: 13) and ZC29,082 (SEQ ID NO: 14). The reaction conditions were as follows: 15 cycles at 94° C. for 1 min., 55° C. for 1 min., 72° C. for 2 min.; followed by 72° C. for 7 min.; then a 4° C. soak. The PCR product was run on a 1% agarose gel and the approximately 400 bp MPL receptor fragment was isolated using Qiaquick™ gel extraction kit (Qiagen) as per manufacturer's instructions.

[0289] The intracellular domain of human zcytor17 was isolated from a plasmid containing zcytor17 receptor cDNA (#23/pCAP) using PCR with primers ZC29,083 (SEQ ID NO: 15) and ZC29,145 (SEQ ID NO: 16). The polynucleotide sequence that corresponds to the zcytor17 receptor coding sequence is shown in SEQ ID NO: 5. The reaction conditions were as per above. The PCR product was run on a 1% agarose gel and the approximately 320 bp zcytor17 fragment isolated using Qiaquick gel extraction kit as per manufacturer's instructions.

[0290] Each of the isolated PCR fragments described above were mixed at a 1:1 volumetric ratio and used in a PCR reaction using ZC6673 (SEQ ID NO: 13) and ZC29145 (SEQ ID NO: 16) to create all but the 5′ MPL portion of the MPL-zcytor17 chimera. The reaction conditions were as follows: 15 cycles at 94° C. for 1 min., 55° C. for 1 min., 72° C. for 2 min.; followed by 72° C. for 7 min.; then a 4° C. soak. The entire PCR product was run on a 1% agarose gel and the approximately 700 bp MPL-zcytor17 chimera fragment isolated using Qiaquick gel extraction kit (Qiagen) as per manufacturer's instructions. The MPL-zcytor17 chimera fragment was digested with BamHI (BRL) and XbaI (Boerhinger Mannheim) as per manufacturer's instructions. The entire digest was run on a 1% agarose gel and the cleaved MPL-zcytor17 chimera isolated using Qiaquick™ gel extraction kit (Qiagen) as per manufacturer's instructions. The resultant cleaved MPL-zvytor17 chimera plus 5′ MPL EcoRI/BamHI. fragment described above were inserted into an expression vector to generate the full MPL-zcytor17 chimeric receptor as described below.

[0291] Recipient expression vector pZP-7 was digested with EcoRI (BRL) and Xbal (BRL) as per manufacturer's instructions, and gel purified as described above. This vector fragment was combined with the EcoRI and XbaI cleaved MPL-zcytor17 PCR chimera isolated above and the EcoRI and BamHI 5′ MPL fragment isolated above in a ligation reaction. The ligation was run using T4 Ligase (Epicentre Technologies), at room temperature for 1 hour as per manufacturer's instructions. A sample of the ligation was electroporated into DH10B ElectroMAX™ electrocompetent E. coli cells (25 μF, 200 Ω, 1.8V). Transformants were plated on LB+Ampicillin plates and single colonies screened by miniprep (Qiagen) and digestion with EcoRI to check for the MPL-zcytor17 chimera. EcoRI digestion of correct clones yield about a 2kb fragment. Confirmation of the MPL-zcytor17 chimera sequence was made by sequence analyses. The insert was approximately 3.1 kb, and was full-length.

[0293] A. Construction of BaF3 Cells Expressing MPL-zcytor17 chimera

[0294] BaF3, an interleukin-3 (IL-3) dependent pre-lymphoid cell line derived from murine bone marrow (Palacios and Steinmetz, Cell 41: 727-734, 1985; Mathey-Prevot et al., Mol. Cell. Biol. 6: 4133-4135, 1986), was maintained in complete media (RPMI medium (JRH Bioscience Inc., Lenexa, Kans.) supplemented with 10% heat-inactivated fetal calf serum, 1-2 ng/ml murine IL-3 (mIL-3) (R & D, Minneapolis, Minn.), 2 mM L-glutaMax-1™ (Gibco BRL), 1 mM Sodium Pyruvate (Gibco BRL), and PSN antibiotics (GIBCO BRL)). Prior to electroporation, pZP-7/MPL-zcytor17 plasmid DNA was prepared and purified using a Qiagen Maxi Prep kit (Qiagen) as per manufacturer's instructions. BaF3 cells for electroporation were washed twice in RPMI media and then resuspended in RPMI media at a cell density of 10⁷ cells/ml. One ml of resuspended BaF3 cells was mixed with 30 μg of the pZP-7/MPL-zcytor17 plasmid DNA and transferred to separate disposable electroporation chambers (GIBCO BRL). At room temperature cells were given 5×0.1 msec shocks at 800 volts followed by 5×2 ms shocks at 600 volts delivered by an electroporation apparatus (Cyto-Pulse). Alternatively, cells were electroporated with two serial pulses (800 μFAD/300 V; followed by 1180 μFAD/300 V) delivered by a Cell-Porator (GibcoBRL) electroporation apparatus. The electroporated cells were transferred to 50 ml of complete media and placed in an incubator for 15-24 hours (37° C., 5% CO2). Then Geneticin™ (Gibco) selection (1 mg/ml G418) was added to the cells in a T-162 flask to isolate the G418-resistant pool. Pools of the transfected BaF3 cells, hereinafter called BaF3/MPL-zcytor17 cells, were assayed for signaling capability as described below.

[0295] B. Testing the Signaling Capability of the BaF3/MPL-zcytor17 Cells Using an Alamar Blue Proliferation Assay

[0296] BaF3/MPL-zcytor17 cells were spun down and washed in the complete media, described above, but without mIL-3 (hereinafter referred to as “mIL-3 free media”). The cells were spun and washed 3 times to ensure the removal of the mIL-3. Cells were then counted in a hemacytometer. Cells were plated in a 96-well format at 5000 cells per well in a volume of 100 μl per well using the mIL-3 free media.

[0297] Proliferation of the BaF3/MPL-zcytor17 cells was assessed using murine thrombopoietin (mTPO) diluted with mIL-3 free media to 200 ng/ml, 100 ng/ml, 50 ng/ml, 25 ng/ml, 12.5 ng/ml, 6.25 ng/ml, 3.1 ng/ml, 1.5 ng/ml concentrations. One hundred microliters of the diluted mTPO was added to the BaF3/MPL-zcytor17 cells. The total assay volume was 200 μl. Negative controls were run in parallel using mIL-3 free media only, without the addition of mTPO. The assay plates were incubated at 37° C., 5% CO₂ for 3 days at which time Alamar Blue (Accumed, Chicago, Ill.) was added at 20 μl/well. Alamar Blue gives a fluorometric readout based on the metabolic activity of cells, and is thus a direct measurement of cell proliferation in comparison to a negative control. Plates were again incubated at 37° C., 5% CO₂ for 24 hours. Plates were read on the Fmax™ plate reader (Molecular Devices Sunnyvale, Calif.) using the SoftMax™ Pro program, at wavelengths 544 (Excitation) and 590 (Emission), or a Wallac Victor 2 plate reader (PerkinElmer Life Sciences, Boston, Mass.).

[0298] Results confirmed the signaling capability of the intracellular portion of the zcytor17 receptor, as the thrombopoietin induced proliferation at approximately 9-13 fold over background at mTPO concentrations of 50 ng/ml and greater.

[0299] Construction of Expression Vector Expressing Full-length zcytor17: pZp7pX/zcytor17

[0300] A. Cloning of Full Length zcytor17 cDNA for Expression:

[0301] To obtain a full-length zcytor17 cDNA, 5′ and 3′ PCR products were isolated and joined using an internal PstI site. The PCR primers were designed using the nucleotide sequence SEQ ID NO: 4 and include BamHI and Xho I restriction sites for cloning purposes.

[0302] A 5′ PCR product was generated using a WI-38 cDNA library as a template and oligonucleotides ZC29,359 (SEQ ID NO: 18) and ZC27,899 (SEQ ID NO: 19) as primers. WI-38 is an in-house cDNA library generated from a human embryonic lung cell line (ATCC CRL-2221). This 5′ PCR reaction was run as follows: 30 cycles at 94° C. for 1 minute, 65° C. for 1 minute, 72° C. for 2 minutes, then 72° C. for 7 minutes; 10° C. soak. The PCR reaction used approximately 3 μg of plasmid prepared from the cDNA library, 20 pmoles of each oligonucleotide, and five units of PWO DNA polymerase (Roche). About 90% of the 5′ PCR product was ethanol precipitated, digested with BamHI and PstI and gel purified on a 1.0% agarose gel. The approximately 600 bp band was excised and used for ligation to the cloning vector pUC18 digested with BamHI and PstI. The resulting transformants were sequenced to confirm the zcytor17 cDNA sequence. For one of these transformants, plasmid DNA was prepared and digested with BamHI and PstI. The resulting approximately 600 bp band was gel purified and used for a ligation below to form a full-length cDNA.

[0303] A 3′ PCR product was generated using a human testes in-house cDNA library as a template and oligonucleotides ZC27,895 (SEQ ID NO: 20) and ZC29,122 (SEQ ID NO: 21) as primers. This 3′ PCR reaction was run as follows: 30 cycles at 94° C. for 45 seconds, 65° C. for 45 seconds, 72° C. for 2 minutes, then 72° C. for 7 minutes; 10° C. soak. The entire 3′ PCR reaction was gel purified on a 1.0% agarose gel and the major 1500 bp band excised. This band was cloned into the PCR Blunt II TOPO vector using the Zeroblunt TOPO kit (Invitrogen). The resulting transformants were sequenced to confirm the zcytor17 cDNA sequence. For one of these transformants, plasmid DNA was prepared and digested with PstI and XhoI. The resulting approximately 1500 bp band was gel purified. A three-part ligation was performed with the 5′ BamHI to Pst I fragment above, the 3′ PstI to XhoI fragment, and the expression vector pZp7pX digested with BamHI and XhoI. This generated a pZp7pX plasmid containing a full-length cDNA for zcytor17 (SEQ ID NO: 4), designated pZp7p/zcytor17. The full length zcytor17 cDNA in pZp7p/zcytor17 has a silent mutation that changes the T to G at position 1888 of SEQ ID NO: 4 (encoding a Gly residue at residue 464 of SEQ ID NO: 5). As this mutation is silent, the zcytor17 cDNA in pZp7p/zcytor17 encodes the polypeptide as shown in SEQ ID NO: 5. Plasmid pZp7pX is a mammalian expression vector containing an expression cassette having the CMV promoter, intron A, multiple restriction sites for insertion of coding sequences, and a human growth hormone terminator. The plasmid also has an E. coli origin of replication, a mammalian selectable marker expression unit having an SV40 promoter, enhancer and origin of replication, a puromycin resistance gene and the SV40 terminator.

[0304] B. Construction of Expression Vector Expressing Full-Length WSX-1

[0305] The entire WSX-1 receptor (SEQ ID NO: 9) was isolated from a plasmid containing the WSX-1 receptor cDNA (SEQ ID NO: 8) (U.S. Pat. No. 5,925,735). hWSX-1/pBluescript SK(+) plasmid DNA (Stratagene, La Jolla, Calif.) was digested with EcoRI and XhoI to generate a 1075 bp fragment, and also digested with XhoI and XbaI to generate a 900 bp fragment. Both digests were run on a 1% agarose gel and the cleaved WSX-1 fragments isolated.

[0306] Recipient expression vector pZp7Z was digested with EcoRI and XbaI and gel purified as described above. This vector fragment was combined with the two cleaved zcytor17 fragments isolated above in a ligation reaction using T4 Ligase (BRL). The ligation was incubated at room temperature overnight. A sample of the ligation was electroporated in to DH10B electroMAX™ electrocompetent E. coli cells (25 μF, 200 Ω, 2.3V). Six colonies were grown in culture and miniprepped DNA was prepared and digested to confirm the correct WSX-1 full-length insert of 2.0 kb. The resulting plasmid is pZPZ7Z/WSX-1.

[0308] A. Construction of BaF3 Cells Expressing zcytor17 Receptor, WSX-1 Receptor and OSMR

[0309] BaF3 cells expressing the full-length zcytor17 receptor were constructed as per Example 2A above, using 30 μg of the zcytor17 expression vector, described in Example 3A. One exception is that in place of Geneticin selection, 2 μg/ml of Puromycin (ClonTech) was added to the transfected cells in a T-162 flask to isolate the puromycin-resistant pool. The BaF3 cells expressing the zcytor17 receptor mRNA were designated as BaF3/zcytor17. To obtain clones, Baf3/zcytor17 cells were counted in a hemocytometer and plated at 1 cell/well, 0.5 cell/well, 0.1 cell/well, and 0.01 cell/well in 96-well dishes. Fifteen clones were scaled up to T75 flasks, and five clones were assayed for zcytor17 expression. Total RNA was isolated from cell pellets using a S.N.A.P.™ total RNA Isolation Kit (InVitrogen). First-strand cDNA was synthesized using the proSTAR™ First Strand RT-PCR kit, and then PCR with zcytor17 specific primers ZC29,180 (SEQ ID NO: 22) and ZC29,122 (SEQ ID NO: 23) was performed to screen the clones for expression of zcytor17. One clone, BaF3/zcytor17#15 was chosen to expand and transfect with the WSX-1 expression vector.

[0310] BaF3 cells expressing zcytor17 and full-length WSX-1 were constructed as per Example 2A above, using 30 μg of the WSX-1 expression vector WSX-1/pZp7Z (Example 3B) to electroporate the BaF3/zcytor17#15 cells. One exception is that in place of Geneticin selection, 200 μg/ml Zeocin (InVitrogen) was added to the transfected cells in a T-162 flask to isolate the zeocin-resistant pool. The BaF3 cells expressing zcytor17 and WSX-1 were designated BaF3/zcytor17/hWSX-1. To obtain clones, pools of Baf3/zcytor17/hWSX-1 cells were plated at limiting dilution in 96-well plates. The resulting clones were expanded and total RNA was isolated using a S.N.A.P.™ total RNA Isolation Kit (InVitrogen). First-strand cDNA was synthesized using the proSTAR™ First Strand RT-PCR kit, and then PCR with WSX-1 specific primers ZC9791 (SEQ ID NO: 24) and ZC9793 (SEQ ID NO: 25) was used to screen the clones for expression of WSX-1. One clone, BaF3/zcytor17/hWSX-1#5 was chosen to expand further and transfect with the OSMRbeta expression vector.

[0311] BaF3 cells expressing zcytor17, WSX-1 and full-length OSMRbeta were constructed as per Example 2A above, using 30 μg of the OSMRbeta expression vector OSMR/pZp7NX described in Example 29 to electroporate the BaF3/zcytor17/hWSX-1#5 cells. The BaF3 cells expressing zcytor17, WSX-1, and OSMRbeta mRNA were designated BaF3/zcytor17/WSX-1/OSMR. To obtain clones, pools of BaF3/zcytor17/WSX-1/OSMRbeta cells were plated at limiting dilution in 96-well plates. Individual clones were expanded and total RNA was isolated using a S.N.A.P.™ total RNA Isolation Kit (In Vitrogen). First-strand cDNA was synthesized using the proSTAR™ First Strand RT-PCR kit, and then PCR with OSMRbeta specific primers ZC40109 (SEQ ID NO: 26) and ZC40112 (SEQ ID NO: 27) was used to screen the clones for expression of zcytor17, WSX-1, and OSMR. One clone, BaF3/zcytor17/WSX-1/OSMR#5 was selected and these cells were used to screen for zcytor17lig as described below in Examples 5 and 6.

[0312] B. Construction of BaF3 Cells Expressing zcytor17 Receptor and OSMR

[0313] BaF3 cells expressing the full-length zcytor17 receptor were constructed as per Example 2A above, using 30 μg of the zcytor17 expression vector, described in Puromycin (ClonTech) was added to the transfected cells in a T-162 flask to isolate the puromycin-resistant pool. The BaF3 cells expressing the zcytor17 receptor mRNA were designated as BaF3/zcytor17. To obtain clones, pools of Baf3/zcytor17 cells were plated at limiting dilution in 96-well plates. These clones were expanded in culture and total RNA was isolated using a S.N.A.P.™ total RNA Isolation Kit (In Vitrogen). First-strand cDNA was synthesized using the proSTAR™ First Strand RT-PCR kit, and then PCR was used to screen the clones for expression of zcytor17. One clone, BaF3/zcytor17 #15 was chosen to expand and transfect with the OSMRbeta expression vector.

[0314] BaF3 cells expressing zcytor17 and full-length OSMRbeta were constructed as per Example 2A above, using 30 μg of the OSMRbeta expression vector OSMR/pZp7NX (example 29) to electroporate the BaF3/zcytor17#15 cells. The BaF3 cells expressing zcytor17 and OSMRbeta mRNA were designated BaF3/zcytor17/OSMR. These cells were used to screen for zcytor17lig as described below in Example 5.

Example 5

[0315] Screening for zcytor17lig Using BaF3/Zcytor17/WSX-1/OSMRbeta Cells Using an Alamar Blue Proliferation Assay

[0316] A. Activation of CCRF-CEM and CCRF-HSB2 Cells to Test for Presence of zcytor17lig

[0317] CCRF-CEM and CCRF-HSB2 cells were obtained from ATCC and stimulated in culture to produce conditioned media to test for the presence of zcytor17lig activity as described below. The suspension cells were seeded at 2×10⁵ cells/ml or 5×10⁵ cells/ml in RPMI-1640 media supplemented with 10% FBS, 2 mM L-glutamine (GibcoBRL), 1× PSN (GibcoBRL), and activated with 10 ng/ml Phorbol-12-myristate-13-acetate (PMA) (Calbiochem, San Diego, Calif.) and 0.5 μg/ml Ionomycin™ (Calbiochem) for 24 or 48 hrs. The supernatant from the stimulated cells was used to assay proliferation of the BaF3/zcytor17/WSX-1/OSMRbeta cells or BaF3/zcytor17/OSMRbeta cells as described below.

[0318] B. Screening for zcytor17lig Using BaF3/Zcytor17/WSX-1/OSMRbeta Cells or BaF3/zcytor17/OSMRbeta Cells Using an Alamar Blue Proliferation Assay

[0319] BaF3/zcytor17/WSX-1/OSMRbeta cells or BaF3/zcytor17/OSMRbeta cells were spun down and washed in mIL-3 free media. The cells were spun and washed 3 times to ensure the removal of the mIL-3. Cells were then counted in a hemacytometer. Cells were plated in a 96-well format at 5000 cells per well in a volume of 100 μl per well using the mIL-3 free media.

[0320] Proliferation of the BaF3/zcytor17/WSX-1/OSMRbeta cells or BaF3/zcytor17/OSMRbeta cells was assessed using conditioned media from activated CCRFCEM and CCRF-HSB2 cells (see Example 5A). Conditioned media was diluted with mIL-3 free media to 50%, 25%, 12.5%, 6.25%, 3.125%, 1.5%, 0.75%, and 0.375% concentrations. 100 μl of the diluted conditioned media was added to the BaF3/zcytor17/WSX-1/OSMRbeta cells or BaF3/zcytor17/OSMRbeta cells. The total assay volume is 200 μl. The assay plates were incubated at 37° C., 5% CO₂ for 3-5 days at which time Alamar Blue (Accumed, Chicago, Ill.) was added at 20 μl/well. Plates were again incubated at 37° C., 5% CO₂ for 24 hours. Plates were read on the Fmax™ plate reader (Molecular devices) as described above (Example 2).

[0321] Results confirmed the proliferative response of the BaF3/zcytor17/WSX-1/OSMRbeta cells or BaF3/zcytor17/OSMRbeta cells to a factor present in the activated CCRF-CEM and CCRF-HSB2 conditioned media. The response, as measured, was approximately 10-fold over background at the 25% concentration. The untransfected BaF3 cells did not proliferate in response to this factor, nor did BaF3 cells transfected with zcytor17 and WSX-1 (BaF3/zcytor17/WXS-1 cells), showing that this factor was specific for Zcytor17/OSMRbeta or zcytor17/OSMRbeta/WSX-1 receptors. Moreover soluble zcytor17 receptor diminished this proliferative activity of zcytor17lig in the BaF3/zcytor17/WSX-1/OSMRbeta cells (see, Example 11). Similar results are expected in BaF3/zcytor17/OSMRbeta cells.

[0322] C. Human Primary Source Used to Isolate zcytor17lig

[0323] One hundred milliliters blood draws were taken from each of six donors. The blood was drawn using 10×10 ml vacutainer tubes containing heparin. Blood was pooled from six donors (600 ml), diluted 1:1 in PBS, and separated using a Ficoll-Paque® PLUS (Pharmacia Biotech). The isolated primary human cell yield after separation on the ficoll gradient was 1.2×10⁹ cells.

[0324] Cells were suspended in 9.6 ml MACS buffer (PBS, 0.5% EDTA, 2 mM EDTA). 1.6 ml of cell suspension was removed and 0.4 ml CD3 microbeads (Miltenyi Biotec, Auburn, Calif.) added. The mixture was incubated for 15 min. at 4° C. These cells labeled with CD3 beads were washed with 30 ml MACS buffer, and then resuspended in 2 ml MACS buffer.

[0325] A VS+ column (Miltenyi) was prepared according to the manufacturer's instructions. The VS+ column was then placed in a VarioMACS™ magnetic field (Miltenyi). The column was equilibrated with 5 ml MACS buffer. The isolated primary human cells were then applied to the column. The CD3 negative cells were allowed to pass through. The column was rinsed with 9 ml (3×3 ml) MACS buffer. The column was then removed from the magnet and placed over a 15 ml falcon tube. CD3+ cells were eluted by adding 5 ml MACS buffer to the column and bound cells flushed out using the plunger provided by the manufacturer. The incubation of the cells with the CD3 magnetic beads, washes, and VS+ column steps (incubation through elution) above were repeated five more times. The resulting CD3+ fractions from the six column separations were pooled. The yield of CD3+ selected human cells were 3×10⁸ total cells.

[0326] A sample of the pooled CD3+ selected human cells was removed for staining and sorting on a fluorescent antibody cell sorter (FACS) to assess their purity. The human CD3+ selected cells were 91% CD3+ cells.

[0327] The human CD3+ selected cells were activated by incubating in RPMI+5% FBS+PMA 10 ng/ml and Ionomycin 0.5 μg/ml (Calbiochem) for 13 hours 37° C. The supernatant from these activated CD3+ selected human cells was tested for zcytor17lig activity as described below. Moreover, the activated CD3+ selected human cells were used to prepare a cDNA library, as described in Example 6, below.

[0328] D. Testing Supernatant From Activated CD3+ Selected Human Cells for zcytor17lig Using BaF3/Zcytor17/WSX-1/OSMRbeta Cells and an Alamar Blue Proliferation Assay

[0329] BaF3/zcytor17/WSX-1/OSMRbeta cells or BaF3/zcytor17/OSMRbeta cells were spun down and washed in mIL-3 free media. The cells were spun and washed 3 times to ensure the removal of the mIL-3. Cells were then counted in a hemacytometer. Cells were plated in a 96-well format at 5000 cells per well in a volume of 100 μl per well using the mIL-3 free media.

[0330] Proliferation of the BaF3/zcytor17/WSX-1/OSMRbeta cells or BaF3/zcytor17/OSMRbeta cells were assessed using conditioned media from activated CD3+ selected human cells (see Example 5C) diluted with mIL-3 free media to 25%, 12.5%, 6.25%, 3.125%, 1.5%, 0.75%, 0.375% and 0.187% concentrations. 100 μl of the diluted conditioned media was added to the BaF3/zcytor17/WSX-1/OSMRbeta cells or BaF3/zcytor17/OSMRbeta cells. The total assay volume was 200 μl. The assay plates were incubated and assayed as described in Example 5B.

[0331] Results confirmed the proliferative response of the BaF3/zcytor17/WSX-1/OSMRbeta cells or BaF3/zcytor17/OSMRbeta cells to a factor present in the activated CD3+ selected human Cell conditioned media. The response, as measured, was approximately 15-fold over background at the 25% concentration. The untransfected BaF3 cells did not proliferate in response to this factor, nor did BaF3 cells transfected with zcytor17 and WSX-1 (BaF3/zcytor17/WXS-1 cells), showing that this factor is specific for Zcytor17/OSMRbeta or zcytor17/OSMRbeta/WSX-1 receptors.

Example 6

[0332] Cloning of Human zcytor17lig From a Human CD3+ Selected Cell Library

[0333] Screening of a primary human activated CD3+ selected cell cDNA library revealed an isolated cDNA that is a novel member of the four-helix bundle cytokine family. This cDNA encoded the zcytor17lig. The cDNA was identified by screening for activity of the zcytor17lig using the zcytor17/WSX-1/OSM receptors.

[0334] A. The Vector for CD3+ Selected Library Construction

[0335] The vector for CD3+ selected. library construction was pZP7NX. The pZP7NX vector was constructed as follows: The coding region for the DHFR selective marker in vector pZP7 was removed by DNA digestion with NcoI and PstI restriction enzymes (Boehringer Mannheim). The digested DNA was run on 1% agarose gel, cut out and gel purified using the Qiagen Gel Extraction Kit (Qiagen) as per manufacturer's instructions. A DNA fragment representing the coding region of Zeocin selective marker was amplified by PCR method with primers ZC13,946 (SEQ ID NO: 28) and ZC13,945 (SEQ ID NO: 29), and pZeoSV2(+) as a template. There are additional PstI and BclI restriction sites in primer ZC13,946 (SEQ ID NO: 28), and additional NcoI and SfuI sites in primer ZC13,945 (SEQ ID NO: 29). The PCR fragment was cut with PstI and NcoI restriction enzymes and cloned into pZP7 vector prepared by cleaving with the same two enzymes and subsequent gel purification. This vector was named pZP7Z. Then the Zeocin coding region was removed by DNA digestion of vector pZP7Z with BclI and SfuI restriction enzymes. The digested DNA was run on 1% agarose gel, cut out and gel purified, and then ligated with a DNA fragment of Neomycin coding region cut from pZem228 vector (deposited at the American Type Culture Collection (ATCC), Manassas, Va.; ATCC Deposit No. 69446) with the same restriction enzymes (BclI and SfuI).

[0336] This new vector was named pZP7N, in which the coding region for DHFR selective marker was replaced by the coding region for a Neomycin selective marker from vector pZem228. A stuffer fragment including an Xho1 site was added to pZP7N to create a vector suitable for high efficiency directional cloning of cDNA; this new vector was called pZP7NX. To prepare the vector for cDNA, 20 μg of pZP7NX was digested with 20 units of EcoR1 (Life Technologies Gaithersberg, Md.) and 20 units of Xho1 (Boehringer Mannheim Indianapolis, Ind.) for 5 hours at 37° C., then 68° C. for 15 minutes. The digest was then run on a 0.8% low melt agarose 1XTAE gel to separate the stuffer from the vector. The vector band was excised and digested with “beta-Agarase” (New England Biolabs, Beverly, Mass.) following the manufacturer's recommendations. After ethanol precipitation the digested vector was resuspended in water to 45 ng/ml in preparation for ligation of CD3+ selected cDNA library described below.

[0337] B. Preparation of Primary Human Activated CD3+ Selected Cell cDNA Library

[0338] Approximately 1.5×10⁸ primary human CD3+ selected cells stimulated in ionomycin/PMA were isolated by centrifugation after culturing at 37° C. for 13 hours (Example 5C). Total RNA was isolated from the cell pellet using the “RNeasy Midi” kit from Qiagen, Inc. (Valencia, Calif.). mRNA was isolated from 225 micrograms of total RNA using the “MPG mRNA purification kit” from CPG Inc. (Lincoln Park, N.J.). 3.4 micrograms of mRNA was isolated and converted to double stranded cDNA using the following procedure.

[0339] First strand cDNA from stimulated human CD3+ selected cells was synthesized as follows. Nine μl Oligo d(T)-selected poly(A) CD3+ RNA at a concentration of 0.34 μg/μl and 1.0 μl of 1 μg/μl first strand primer ZC18,698 (SEQ ID NO: 30) containing an XhoI restriction site were mixed and heated at 65° C. for 4 minutes and cooled by chilling on ice. First strand cDNA synthesis was initiated by the addition of 9 μl of first strand buffer (5× SUPERSCRIPT® buffer; (Life Technologies), 4 μl of 100 mM dithiothreitol and 2 μl of a deoxynucleotide triphosphate solution containing 10 mM each of dATP, dGTP, dTTP and 5-methyl-dCTP (Pharmacia Biotech Inc.) to the RNA-primer mixture. The reaction mixture was incubated at 45° C. for 4 minutes followed by the addition of 8 μl of 200 U/μl SuperscriptII®, RNase H-reverse transcriptase (Life technologies). The reaction was incubated at 45° C. for 45 minutes followed by an incubation ramp of 1° C. every 2 minutes to 50° C. where the reaction was held for 10 minutes. To denature any secondary structure and allow for additional extension of the cDNA the reaction was then heated to 70° C. for 2 minutes then dropped to 55° C. for 4 minutes after which 2 μl of SuperscriptII® RT was added and incubated an additional 15 minutes followed by a ramp up to 70° C. 1 minute/1° C. Unincorporated nucleotides were removed from the cDNA by twice precipitating in the presence of 2 μg of glycogen carrier, 2.0 M ammonium acetate and 2.5 volume ethanol, followed by a 100 μl wash with 70% ethanol. The cDNA was resuspended in 98 μl water for use in second strand synthesis.

[0340] Second strand synthesis was performed on the first strand cDNA under conditions that promoted first strand priming of second strand synthesis resulting in DNA hairpin formation. The second strand reaction contained 98 μl of the first strand cDNA, 30 μl of 5× polymerase I buffer (100 mM Tris: HCl, pH 7.5, 500 mM KCl, 25 mM MgCl₂, 50 mM (NH₄)₂SO₄), 2 μl of 100 mM dithiothreitol, 6 μl of a solution containing 10 mM of each deoxynucleotide triphosphate, 5 μl of 5 mM b-NAD, 1 μl of 3 U/μl E. coli DNA ligase (New England Biolabs Inc.) and 4 μl of 10 U/μl E. coli DNA polymerase I (New England Biolabs Inc.). The reaction was assembled at room temperature and was incubated at room temperature for 2 minutes followed by the addition of 4 μl of 3.8 U/μl RNase H (Life Technologies). The reaction was incubated at 15° C. for two hours followed by a 15 minute incubation at room temperature. 10 μl of 1M TRIS pH7.4 was added to the reaction and extracted twice with phenol/chloroform and once with chloroform, the organic phases were then back extracted with 50 μl of TE (10 mM TRIS pH 7.4, 1 mM EDTA), pooled with the other aqueous and ethanol precipitated in the presence of 0.3 M sodium acetate. The pellet was washed with 100 μl 70% ethanol air dried and resuspended in 40 μl water.

[0341] The single-stranded DNA of the hairpin structure was cleaved using mung bean nuclease. The reaction mixture contained 40 μl of second strand cDNA, 5 μl of 10× mung bean nuclease buffer (Life technologies), 5 μl of mung bean nuclease (Pharmacia Biotech Corp.) diluted to 1U/μl in 1× mung bean nuclease buffer. The reaction was incubated at 37° C. for 45 minutes. The reaction was terminated by the addition of 10 μl of 1 M Tris: HCl, pH 7.4 followed by sequential phenol/chloroform and chloroform extractions as described above. Following the extractions, the cDNA was ethanol precipitated in the presence of 0.3 M sodium acetate. The pellet was washed with 100 μl 70% ethanol air dried and resuspended in 38 μl water.

[0342] The resuspended cDNA was blunt-ended with T4 DNA polymerase. The cDNA, which was resuspended in 38 μl of water, was mixed with 12 μl 5× T4 DNA polymerase buffer (250 mM Tris:HCl, pH 8.0, 250 mM KCl, 25 mM MgCl₂), 2 μl 0.1 M dithiothreitol, 6 μl of a solution containing 10 mM of each deoxynucleotide triphosphate and 2 μl of 1 U/μl T4 DNA polymerase (Boehringer Mannheim Corp.). After an incubation of 45 minutes at 15° C., the reaction was terminated by the addition of 30 μl TE followed by sequential phenol/chloroform and chloroform extractions and back extracted with 20 μl TE as described above. The DNA was ethanol precipitated in the presence of 2 μl Pellet Paint™ (Novagen) carrier and 0.3 M sodium acetate and was resuspended 11 μl of water.

[0343] EcoRI adapters were ligated onto the 5′ ends of the cDNA described above to enable cloning into an expression vector. 11 μl of cDNA and 4 μl of 65 pmole/μl of Eco RI hemiphophorylated adaptor (Pharmacia Biotech Corp) were mixed with 5 μl 5× ligase buffer (Life Technologies), 2 μl of 10 mM ATP and 3 μl of 1 U/μl T4 DNA ligase (Life Technologies), 1 μl 10× ligation buffer (Promega Corp), 9 μl water. The extra dilution with 1× buffer was to prevent the pellet paint from precipitating. The reaction was incubated 9 hours in a water bath temperature ramp from 10° C. to 22° C. over 9 hours, followed by 45 minutes at 25° C. The reaction was terminated by incubation at 68° C. for 15 minutes.

[0344] To facilitate the directional cloning of the cDNA into an expression vector, the cDNA was digested with XhoI, resulting in a cDNA having a 5′ Eco RI cohesive end and a 3′ XhoI cohesive end. The XhoI restriction site at the 3′ end of the cDNA had been previously introduced using the ZC18698 (SEQ ID NO: 31) primer. Restriction enzyme digestion was carried out in a reaction mixture containing 35 μl of the ligation mix described above, 6 μl of 10×H buffer (Boehringer Mannheim Corp.), 1 μl of 2 mg/ml BSA (Biolabs Corp.), 17 μl water and 1.0 μl of 40 U/μl XhoI (Boehringer Mannheim). Digestion was carried out at 37° C. for 1 hour. The reaction was terminated by incubation at 68° C. for 15 minutes followed by ethanol precipitation, washing drying as described above and resuspension in 30 μl water.

[0345] The resuspended cDNA was heated to 65° C. for 5 minutes and cooled on ice, 4 μl of 5× gel loading dye (Research Genetics Corp.) was added, the cDNA was loaded onto a 0.8% low melt agarose 1× TAE gel (SEA PLAQUE GTG™ low melt agarose; FMC Corp.) and electrophoresed. The contaminating adapters and cDNA below 0.6 Kb in length were excised from the gel. The electrodes were reversed, molten agarose was added to fill in the wells, the buffer was changed and the cDNA was electrophoresed until concentrated near the lane origin. The area of the gel containing the concentrated cDNA was excised and placed in a microfuge tube, and the agarose was melted by heating to 65° C. for 15 minutes. Following equilibration of the sample to 45° C., 2 μl of 1 U/μl Beta-agarase I (Biolabs, Inc.) was added, and the mixture was incubated for 90 min. at 45° C. to digest the agarose. After incubation, 1 tenth volume of 3 M Na acetate was added to the sample, and the mixture was incubated on ice for 15 minutes. The sample was centrifuged at 14,000× g for 15 minutes at room temperature to remove undigested agarose, the cDNA was ethanol precipitated, washed in 70% ethanol, air-dried and resuspended in 40 μl water.

[0346] To determine the optimum ratio of cDNA to vector several ligations were assembled and electroporated. Briefly, 2 μl of 5× T4 ligase buffer (Life Technologies), 1 μl of 10 mM ATP, 1 μl pZP7NX digested with EcoR1-Xho1, 1 μl T4 DNA ligase diluted to 0.25u/μl (Life Technologies) water to 10 μl and 0.5, 1,2 or 3 μl of cDNA were mixed in 4 separate ligations, incubated at 22° C. for 4 hours, 68° C. for 20 minutes, sodium acetate-ethanol precipitated, washed, dried and resuspended in 10 μl. A single microliter of each ligation was electroporated into 40 μl DH10b ElectroMax™ electrocompetent bacteria (Life Technologies) using a 0.1 cm cuvette (Biorad) and a Genepulser, pulse controller™ (Biorad) set to 2.5 KV, 25 lF, 200 ohms. These cells were immediately resuspended in 1 ml SOC broth (Manniatis et al. supra.) followed by 500 μl of 50% glycerol-SOC as a preservative. These “glycerol stocks” were frozen in several aliquots at −70° C. An aliquot of each was thawed and plated serially on LB-agar plates supplemented with ampicillin at 100 μg/ml. Colony numbers indicated that the optimum ratio of CD3+ cDNA to pZP7NX vector was 1 μl to 45 ng; such a ligation yielded 4.5 million primary clones.

[0347] For the purpose of screening the library using a BaF3-based proliferation assay (Example 5) glycerol stocks from above were diluted into liquid cultures of 100 or 250 clones per pool in deep well microtiter plates, grown 24 hours at 37° C. with shaking and plasmid isolated using a Qiagen kit following the manufacturer's instructions. Such DNA was subsequently transfected into BHK cells, media conditioned 72 hours, harvested and stored at −80° C., and subsequently placed on 5K BaF3/zcytor17/WSX-1/OSMRbeta cells or BaF3/zcytor17/OSMRbeta cells for 72 hours after which proliferation was assessed using an “Alamar blue” fluorescence assay (Example 5B and Example 2B).

Example 7

[0348] Expression Cloning of Human zcytor17lig

[0349] The glycerol stocks from the activated human CD3+ selected cell library (Example 6) were added to Super Broth II™ (Becton Dickinson, Cockeysville, Md.) +0.1 mg/ml ampicillin (amp) at a concentration of 250 cells per 800 microliters. The E. coli were allowed to equilibrate for 24 hours at room temperature. At the time of inoculation, 400 microliters was plated on LB+amp plates to determine the actual titer of the inoculation. After 24 hours the plates were counted and then the final concentration of the SuperBrothII™+E. coli was adjusted so that the final concentration was 250 cells per 1.2 ml. Three times 2 liters were inoculated for a total of 6 liters. The media were then plated into 96-well deep well blocks (Qiagen). Plating was done on the 8-channel Q-Fill2™ dispenser (Genetix, Christchurch, Dorset, UK). The E. coli were grown overnight at 37° C. shaking at 250 rotations/min. on a New Brunswick Scientific Innova 4900 multi-tier environment shaker. The E. coli were spun out of solution at 3000 rpm, using a Beckman GS-6KR centrifuge. These E. coli pellets were frozen at −20° C. or used fresh before miniprepping the plasmid DNA. Each pellet contains approximately 250 cDNA clones from the human CD3+ selected cell library.

[0350] These pools of 250 cDNA clones were then mini-prepped using QIAprep™ 96 Turbo Miniprep kit (Qiagen). Plasmid DNA was eluted using 125 μl of TE (10 mM Tris pH 8, 1 mM EDTA). This plasmid DNA was then used to transfect BHK cells.

[0351] BHK Transfection

[0352] BHK cells were plated in 96-well tissue culture plates at a density of 12,000 cells per well in a volume of 100 μl. per well. Culture media was DMEM (GibcoBRL), 5% heat-inactivated fetal bovine serum, 2 mM L-glutamine (GibcoBRL), 1× PSN (GibcoBRL), 1 mM NaPyruvate (GibcoBRL).

[0353] The following day, BHK cells were washed once with 100 μl SFA. SFA is serum-free media which is DMEM/F12 or DMEM (Gibco/BRL), 2 mM GlutaMax™ (Gibco/BRL), 1 mM NaPyruvate, 10 μg/ml transferrin, 5 μg/ml insulin, 10 μg/ml fetuin, 2 μg/ml selenium, 25 mM HEPES (Gibco/BRL), 100 μM non-essential amino acids (Gibco/BRL).

[0354] A DNA/Lipofectamine™ mix was made as follows: 2.2 μl Lipofectamine™ reagent (Gibco/BRL) was combined with 102.8 μl SFA at room temperature; approximately 5 μl of the plasmid DNA (200 ng/μl) was then added to the Lipofectamine™/SFA to form the DNA/Lipofectamine™ mixture, which was incubated at room temperature for 30 minutes. The SFA was removed from the BHK cells and the cells were incubated with 50 μl of the DNA/lipofectamine™ mix for 5 hours at 37° C. with 5% CO₂. Fifty μl of the DNA/Lipofectamine™ mixture was added to each of two wells of the BHK cells, so that transfections were done in duplicate.

[0355] After BHK cells were incubated with DNA/Lipofectamine™ mix for 5 hours, the DNA/Lipofectamine™ mix was removed and 100 μl culture media was added. Cells were incubated overnight, the media was removed and replaced with 100 μl. culture media. After culturing cells for 48-72 hours, conditioned media was removed, frozen at −80° C. for a minimum of 20 minutes, thawed, and then 50 μl was assayed in the Baf3 proliferation assay, described in Example 5, to identify pools of 250 clones with ligand activity.

[0356] Twenty 96-well plates were screened in a single assay. This represented approximately 250 cDNAs/well or 480,000 cDNAs total. Of these, conditioned media from approximately 60 wells (representing 250 cDNAs per well) tested positive in the proliferation assay. One of these positive pools was chosen to break down and isolate a single cDNA that would encode the zcytor17lig. This was pool 62A12.

[0357] For pool 62A12, 1 μl. of DNA was used to transform ElectroMax™ DH10B cells (Gibco/BRL) by electroporation. The transformants were plated on LB+amp (100 μg/ml) plates to give single colonies. From the electroporated pool, 672 individual colonies were selected by toothpick into seven 96-well plates containing 1.2 ml of SuperBrothII™ per well. These plates were numbered #62.1 through #62.7. These were cultured overnight and the plasmid DNA miniprepped as above. For all seven plates, plasmid DNA from the breakdown plates was transfected into BHK cells and assayed by proliferation as above, except that transfections were not done in duplicate.

[0358] Two positive clones 62.6C7 and 62.6E9 were identified by activity from a total of 672 clones. Plasmid DNA miniprepped from clone 62.6E9 was sequenced and a tentative identification was obtained, but a mixed sequence was obtained from this positive clones. To further isolate the zcytor17lig cDNA to a single clone, 1 μl of DNA from pool 62.6E9 was used to electroporate DH10B cells and the transformants plated on LB+amp (100 μg/ml) plates to give single colonies. Plasmid DNA miniprepped from several colonies was sequenced to give the exact DNA sequence. The polynucleotide sequence of zcytor17lig was full-length (SEQ ID NO: 1) and its corresponding amino acid sequence is shown (SEQ ID NO: 2).

[0359] Construction of Mammalian Expression Vectors That Express zcytor17 Soluble Receptors: zcytor17CEE, zcytor17CFLG, zcytor17CHIS and zcytor17-Fc4

[0360] A. Construction of zcytor17 Mammalian Expression Vector Containing zcytor17CEE, zcytor17CFLG and zcytor17CHIS

[0361] An expression vector was prepared for the expression of the soluble, extracellular domain of the zcytor17 polypeptide, pZp9zcytor17CEE, where the construct is designed to express a zcytor17 polypeptide comprised of the predicted initiating methionine and truncated adjacent to the predicted transmembrane domain, and with a C-terminal Glu-Glu tag (SEQ ID NO: 32).

[0362] An approximately 1500 bp PCR product was generated using ZC29,451 (SEQ ID NO: 33) and ZC29,124 (SEQ ID NO: 34) as PCR primers to add EcoRI and BamHI restriction sites. A human HPVS in-house cDNA library was used as a template and PCR amplification was performed as follows: 30 cycles at 94° C. for 1 minute, 65° C. for 1 minute, 72° C. for 1.5 minutes, then 72° C. for 7 minutes; 10° C. soak. The PCR reaction was ethanol precipitated and digested with EcoRI and BamHI restriction enzymes. The digested PCR product was gel purified on a 1.0% agarose gel and the approximately 1500 bp band excised. This band was then re-amplified using identical primers with the following cycling: 30 cycles at 94° C. for 1 minute, 65° C. for 1 minute, 72° C. for 3 minutes, then 72° C. for 7 minutes; 10° C. soak. The PCR reaction was ethanol precipitated and digested with EcoRI and BamHI restriction enzymes. The digested PCR product was gel purified on a 1.0% agarose gel and the approximately 1500 bp band excised. The excised DNA was subcloned into plasmid CEEpZp9 that had been cut with EcoRI and BamHI, to generate plasmid with a GLU-GLU C-terminally tagged soluble receptor for zcytor17, zcytor17CEEpZp9. The extracellular domain in the zcytor17CEE cDNA in zcytor17CEEpZp9 has a silent mutation that changes the T to C at position 1705 of SEQ ID NO: 4 (encoding a Pro residue at residue 403 of SEQ ID NO: 5). As this mutation is silent, the zcytor17 cDNA in zcytor17CEEpZp9 encodes the polypeptide as shown in SEQ ID NO: 5. Moreover, because of the construct used, a Gly-Ser residue pair is inserted C-terminal to the end of the soluble, extracellular domain of zcytor17 and prior to the C-terminal Glu-Glu Tag (SEQ ID NO: 32). As such, the tag at the C-terminus of the zcytor17 extracellular domain, was a Glu-Glu tag as shown in (SEQ ID NO: 17). Plasmid CEEpZp9 is a mammalian expression vector containing an expression cassette having the mouse metallothionein-1 promoter, multiple restriction sites for insertion of coding sequences, and a human growth hormone terminator. The plasmid also has an E. coli origin of replication, a mammalian selectable marker expression unit having an SV40 promoter, enhancer and origin of replication, a DHFR gene and the SV40 terminator. Using standard molecular biological techniques zcytor17CEEpZp9 was electroporated into DH10B competent cells (GIBCO BRL, Gaithersburg, Md.) according to manufacturer's direction and plated onto LB plates containing 100 μg/ml ampicillin, and incubated overnight. Colonies were screened by restriction analysis, or PCR from DNA prepared from individual colonies. The insert sequence of positive clones was verified by sequence analysis. A large scale plasmid preparation was done using a QIAGEN® Maxi prep kit (Qiagen) according to manufacturer's instructions.

[0363] The same process is used to prepare the zcytor17 soluble receptors with a C-terminal his tag, composed of 6 His residues in a row; and a C-terminal FLAG® tag (SEQ ID NO: 36), zcytor17CFLAG. To construct these constructs, the aforementioned vector has either the HIS or the FLAG® tag in place of the glu-glu tag (e.g., SEQ ID NO: 17; SEQ ID NO: 32 or SEQ ID NO: 35).

[0364] B. Mammalian Expression Construction of Soluble Human zcytor17 Receptor: zcytor17-Fc4

[0365] An expression vector, pEZE-2 hzcytor17/Fc4, was prepared to express a C-terminally Fc4 tagged soluble version of hzcytor17 (human zcytor17-Fc4) in PF CHO cells. PF CHO cells are an in house CHO cell line adapted for growth in protein-free medium (ExCell 325 PF medium; JRH Biosciences). The in house CHO cell line was originally derived from CHO DG44 cells (G. Urlaub, J. Mitchell, E. Kas, L. A. Chasin, V. L. Funanage, T. T. Myoda and J. L. Hamlin, “The Effect Of Gamma Rays at the Dihydrofolate Reductase Locus: Deletions and Inversions,” Somatic Cell and Molec. Genet., 12: 555-566 (1986). A fragment of zcytor17 cDNA that includes the polynucleotide sequence from extracellular domain of the zcytor17 receptor was fused in frame to the Fc4 polynucleotide sequence (SEQ ID NO: 37) to generate a zcytor17-Fc4 fusion (SEQ ID NO: 38 and SEQ ID NO: 39). The pEZE-2 vector is a mammalian expression vector that contains the Fc4 polynucleotide sequence and a cloning site that allows rapid construction of C-terminal Fc4 fusions using standard molecular biology techniques.

[0366] A 1566 base pair fragment was generated by PCR, containing the extracellular domain of human zcytor17 and the first two amino acids of Fc4 (Glu and Pro) with FseI and BglII sites coded on the 5′ and 3′ ends, respectively. This PCR fragment was generated using primers ZC29,157 (SEQ ID NO: 40) and ZC29,150 (SEQ ID NO: 41) by amplification from a plasmid containing the extracellular domain of human zcytor17 (pZp9zcytor17CEE) (Example 8). The PCR reaction conditions were as follows: 25 cycles of 94° C. for 1 minute, 60° C. for 1 minute, and 72° C. for 2 minutes; 1 cycle at 72° C. for 10 minutes; followed by a 4° C. soak. The fragment was digested with FseI and BglII restriction endonucleases and subsequently purified by 1% gel electrophoresis and band purification using QiaQuick gel extraction kit (Qiagen). The resulting purified DNA was ligated for 5 hours at room temperature into a pEZE-2 vector previously digested with FseI and BglII containing Fc4 3′ of the FseI and BglII sites.

[0367] Two μl of the ligation mix was electroporated in 37 μl DH10B electrocompetent E. coli (Gibco) according to the manufacturer's directions. The transformed cells were diluted in 400 μl of LB media and plated onto LB plates containing 100 μg/ml ampicillin. Clones were analyzed by restriction digests and positive clones were sent for DNA sequencing to confirm the sequence of the fusion construct. 1 μl of a positive clone was transformed into 37 μl of DH10B electrocompetent E. coli and streaked on a LB/amp plate. A single colony was picked from this streaked plate to start a 250 ml LB/amp culture that was then grown overnight at 37° C. with shaking at 250 rpm. This culture was used to generate 750 μg of purified DNA using a Qiagen plasmid Maxi kit (Qiagen).

[0368] Transfection and Expression of Zcytor17 Soluble Receptor Polypeptides

[0369] BHK 570 cells (ATCC No. CRL-10314), DG-44 CHO, or other mammalian cells are plated at about 1.2×10⁶ cells/well (6-well plate) in 800 μl of appropriate serum free (SF) media (e.g., DMEM, Gibco/BRL High Glucose) (Gibco BRL, Gaithersburg, Md.). The cells are transfected with expression plasmids containing zcytor17CEE, zcytor17CFLG, zcytor17CHIS or zcytor17-Fc4 (Example 8), using Lipofectin™ (Gibco BRL), in serum free (SF) media according to manufacturer's instruction. Single clones expressing the soluble receptors are isolated, screened and grown up in cell culture media, and purified using standard techniques.

[0370] A. Mammalian Expression of Soluble Human zcytor17CEE Receptor

[0371] BHK 570 cells (ATCC NO: CRL-10314) were plated in T-75 tissue culture flasks and allowed to grow to approximately 50 to 70% confluence at 37° C., 5% CO₂, in DMEM/FBS media (DMEM, Gibco/BRL High Glucose, (Gibco BRL, Gaithersburg, Md.), 5% fetal bovine serum, 1 mM L-glutamine (JRH Biosciences, Lenea, Kans.), 1 mM sodium pyruvate (Gibco BRL)). The cells were then transfected with the plasmid containing zcytor17CEE (Example 8) using Lipofectamine™ (Gibco BRL), in serum free (SF) media formulation (DMEM, 10 mg/ml transferrin, 5 mg/ml insulin, 2 mg/ml fetuin, 1% L-glutamine and 1% sodium pyruvate). Ten μg of the plasmid DNA pZp9zcytor17CEE (Example 8) was diluted into a 15 ml tube to a total final volume of 500 μl with SF media. 50 μl of Lipofectamine was mixed with 450 μl of SF medium. The Lipofectamine mix was added to the DNA mix and allowed to incubate approximately 30 minutes at room temperature. Four ml of SF media was added to the DNA:Lipofectamine mixture. The cells were rinsed once with 5 ml of SF media, aspirated, and the DNA:Lipofectamine mixture was added. The cells were incubated at 37° C. for five hours, and then 5 ml of DMEM/10%FBS media was added. The flask was incubated at 37° C. overnight after which time the cells were split into the selection media (DMEM/FBS media from above with the addition of 1 μM methotrexate or 10 μM Methotrexate (Sigma Chemical Co., St. Louis, Mo.) in 150 mm plates at 1:2, 1:10, and 1:50. Approximately 10 days post-transfection, one 150 mm plate of 1 μM methotrexate resistant colonies was trypsinized, the cells were pooled, and one-half of the cells were replated in 10 μM methotrexate; to further amplify expression of the zcytor17CEE protein. A conditioned-media sample from this pool of amplified cells was tested for expression levels using SDS-PAGE and Western analysis.

[0372] B. Mammalian Expression of Soluble Human zcytor17-Fc4 Receptor

[0373] Five replicates of 200 μg of pEZE-2hzcytor17Fc4 plasmid DNA (Example 8) were linearized by restriction digestion with FspI, a restriction enzyme that cuts once within the vector and does not disturb genes necessary for expression. 200 μg of CHO cell genomic DNA was added to each replicate as carrier DNA and then the DNA was precipitated by addition of 0.1 volumes of 3M Sodium Acetate pH 5.2 and 2.2 volumes ethanol followed by a 15 minute ice incubation and microcentrifugation at 4° C. The resulting DNA pellets were washed in 70% ethanol and air dried before being resuspended in 100 μl protein free (PF) CHO non-selection growth media (21 g/L PF CHO Ex Cell 325/200 mM L-glutamine (Gibco)/100 mM sodium pyruvate (Gibco)/1× HT Supplement (Gibco). Ten million PF CHO passage 61 cells were added to the DNA in 600 μl of PF CHO non-selection growth media and then electroporated in a Gene Pulser II Electroporation system (BioRad) using 950 μF capacitance and 300 Kv using a 0.4 cm gap Gene Pulser (BioRad) electroporation cuvette. All 5 replicates of the electroporated cells were pooled and directly selected in -HT media (21 g/L PF CHO Ex Cell 325/200 mM L-glutamine (Gibco)/100 mM sodium pyruvate (Gibco). Cells were selected for 15 days in -HT media before being passaged at 4×10⁵ ml into 50 nm MTX selection. Eight days later cells were seeded at 3.5×10⁵ cells/ml into 200 mM MTX selection. After one week, cells were seeded at 4×10⁵ cells/ml into 1 μM MTX selection. After two weeks at 1 μM MTX, cells were seeded at 1×10⁶ cells/ml into 50 ml to generate conditioned medium. The resulting 72 hour conditioned media was analyzed by probing western blots with an antibody generated against human Ig. The cells produced hzcytor17/Fc4 protein at approximately 1 mg/L.

[0374] C. Larger-Scale Mammalian Expression of Soluble Human zcytor17-Fc4 Receptor

[0375] Two hundred micrograms of pEZE-2hzcytor17Fc4 plasmid DNA (Example 8) was linearized by restriction digestion with FspI, a restriction enzyme that cuts once within the pEZE-2 vector and does not disturb genes necessary for expression. 200 μg of CHO genomic DNA (prepared in-house) was added as carrier DNA and then the DNA was precipitated by addition of 0.1 volumes of 3M Sodium Acetate pH 5.2 and 2.5 volumes ethanol followed by microcentrifugation at Room temperature. Five replicate DNA pellets were made and transformed. The resulting DNA pellet was washed in 70% ethanol and air dried before being resuspended in 100 μl PF CHO non-selection growth media (21 g/L PF CHO Ex Cell 325/200 mM L-glutamine (Gibco)/100 mM sodium pyruvate (Gibco)/1× HT Supplement (Gibco). Ten million PF CHO cells were added to the DNA in 600 μl of PF CHO non-selection growth media and then electroporated in a Gene Pulser II Electroporation system (BioRad) using 950 μF capacitance and 300 volts using a 0.4 cm gap Gene Pulser (BioRad) electroporation cuvette. The electroporated cells were pooled and put directly into selection in -HT media (21 g/L PF CHO Ex Cell 325/200 mM L-glutamine (Gibco)/100 mM sodium pyruvate (Gibco). Cells were selected for 14 days in -HT media before being passaged at 4×10⁵/ml into 50 nm MTX selection. Cells were amplified to 200 nM MTX and then to 1 uM MTX. The -HT, 50 nM, and 1 uM pools were seeded at 1×10⁶ c/ml for 48 hours, and the resulting conditioned media was analyzed by probing western blots with an antibody generated against human Ig.

[0376] Purification of zcytor17 Soluble Receptors From BHK 570 and CHO Cells

[0377] A. Transient Mammalian Expression and Purification of Soluble Human zcytor17-Fc4 Receptor

[0378] pEZE-2hzcytor17Fc4 plasmid DNA (Example 11B) was introduced into 40 maxi plates of BHK cells using Lipofectamine (Gibco BRL) as described herein and in manufacturer's instructions. Cells were allowed to recover overnight, then were rinsed and refed with serum-free medium (SL7V4, made in-house). After 72 hours, the media was collected and filtered, and cells were refed with serum-free medium. After 72 hours, the media was again collected and filtered.

[0379] The serum-free conditioned media (2×1.5 L batches) from transiently transfected BHK cells was pumped over a 1.5 ml Protein A-agarose column in 20 mM Tris, pH 7.5, 0.5 M NaCl. The column was washed extensively with this buffer and then the bound protein was eluted with 1 ml of 0.2 M glycine, pH 2.5, 0.5 M NaCl. The eluted protein was collected into 0.1 ml of 2 M Tris, pH 8.5.

[0380] Aliquots were collected for SDS-polyacrylamide gel electrophoresis and the bulk zcytor17-Fc was dialyzed overnight against PBS. The soluble receptor was sterile filtered and placed in aliquots at −80° C.

[0381] B. Purification of zcytor17-Fc4

[0382] Recombinant carboxyl terminal Fc4 tagged zcytor17 (Example 8 and Example 9) was produced from transfected CHO cells. The CHO transfection was performed using methods known in the art. Approximately five-liters of conditioned media were harvested and sterile filtered using Nalgene 0.2 μm filters.

[0383] Protein was purified from the filtered media by a combination of Poros 50 protein A affinity chromatography (PerSeptive Biosystems, 1-5559-01, Framingham, Mass.) and Superdex 200 gel exclusion chromatography column (Amersham Pharmacia Biotech, Piscataway, N.J.). Culture medium was directly loaded onto a 10 ×70 mm (5.5-ml bed volume) protein A affinity column at a flow of about 3-10 ml/minute. Following column washing for ten column volumes of PBS, bound protein was eluted by five column volumes of 0.1 M glycine, pH 3.0 at 10 ml/minute). Fractions of 2 ml each were collected into tubes containing 100 μl of 2.0 M Tris, pH 8.0, in order to neutralize the eluted proteins. Samples from the affinity column were analyzed by SDS-PAGE with coomassie staining and Western blotting for the presence of zcytor17-Fc4 using human Ig-HRP. Zcytor17-Fc4-containing fractions were pooled and concentrated to 1-2 ml using Biomax-30 concentrator (Millipore), and loaded onto a 20×580 mm Superdex 200 gel filtration column. The fractions containing purified zcytor17-Fc4 were pooled, filtered through 0.2 μm filter, aliquoted into 100 μl each, and frozen at −80° C. The concentration of the final purified protein was determined by BCA assay (Pierce, Rockford, Ill.).

[0384] C. SDS-PAGE and Western Blotting Analysis of zcytor17/Fc4

[0385] Recombinant zcytor17-Fc4 was analyzed by SDS-PAGE (Nupage 4-12%, Invitrogen, Carlsbad, Calif.) with coomassie staining method and Western blotting using human Ig-HRP. Either the conditioned media or purified protein was electrophoresed using an Invitrogen Novex's Xcell II mini-cell, and transferred to nitrocellulose (0.2 mm; Invitrogen, Carlsbad, Calif.) at room temperature using Novex's Xcell II blot module with stirring according to directions provided in the instrument manual. The transfer was run at 500 mA for one hour in a buffer containing 25 mM Tris base, 200 mM glycine, and 20% methanol. The filters were then blocked with 10% non-fat dry milk in PBS for 10 minutes at room temperature. The nitrocellulose was quickly rinsed, then the human Ig-HRP antibody (1:2000) was added in PBS containing 2.5% non-fat dry milk. The blots were incubated for two hours at room temperature, or overnight at 4° C., with gentle shaking. Following the incubation, the blots were washed three times for 10 minutes each in PBS, then quickly rinsed in H₂O. The blots were developed using commercially available chemiluminescent substrate reagents (SuperSignal® ULTRA reagents 1 and 2 mixed 1:1; reagents obtained from Pierce, Rockford, Ill.), and the signal was captured using Lumi-Imager's Lumi Analyst 3.0 software (Boehringer Mannheim GmbH, Germany) for exposure times ranging from 10 second to 5 minutes or as necessary.

[0386] The purified zcytor17-Fc4 appeared as a single band with either the coomassie or silver staining at about 220 kDa under non-reducing conditions, and at about 120 kDa under reducing conditions, suggesting the dimeric form of zcytor17-Fc4 under non-reducing conditions as expected.

Example 11

[0387] Assay Using zcytor17 Soluble Receptor zcytor17-Fc4 Soluble Receptor in Competitive Inhibition Assay

[0388] BaF3/zcytor17/WSX-1/OSMRbeta cells or BaF3/zcytor17/OSMRbeta cells were spun down and washed in mIL-3 free media. The cells were spun and washed 3 times to ensure the removal of the mIL-3. Cells were then counted in a hemacytometer. Cells were plated in a 96-well format at 5000 cells per well in a volume of 100 μl per well using the mIL-3 free media.

[0389] Both conditioned media from the CCRF-CEM and CCRF-HSB2 cell activation and the human CD3+ selected cells, described in Example 5, were added in separate experiments at 25%, 12.5%, 6.25%, 3.125%, 1.5%, 0.75%, 0.375%, and 0.187% concentrations, with or without zcytor17 soluble receptors (Zcytor17-Fc4; See, Example 9 and Example 10) at 1-10 μg/ml. The total assay volume was 200 μl.

[0390] The assay plates were incubated at 37° C., 5% CO₂ for 3-5 days at which time Alamar Blue (Accumed) was added at 20 μl/well. Plates were again incubated at 37° C., 5% CO₂ for 16-24 hours. Plates were read on the Fmax™ plate reader (Molecular Devices) as described in Example 2. Results demonstrated partial inhibition of cell growth with zcytor17-Fc4 soluble receptor at 10 μg/ml, confirming that the factor in each sample was specific for the zcytor17 receptor.

[0391] Titration curves, diluting out the soluble receptor, or soluble receptor heterodimers and trimers comprising zcytor17 receptor (e.g., zcytor17/OSMR, zcytor17/WSX-1, or zcytor17/OSMR/WSX-1, or other Class I cytokine receptor subunits) are also run using the above stated assay to determine whether zcytor17 receptors are able to completely inhibit growth, for example, at low or physiologic concentrations.

Example 12

[0392] Secretion Trap Assay

[0393] A secretion trap assay is used to test the binding of the zcytor17lig to receptors comprising zcytor17 receptor, such as the zcytor17 receptor or receptor heterodimers and trimers comprising zcytor17 receptor (e.g., zcytor17/OSMR, zcytor17/WSX-1, or zcytor17/OSMR/WSX-1, or other Class I cytokine receptor subunits). Zcytor17lig plasmid DNA is transfected into COS cells, and used to assess binding of the zcytor17lig to receptors comprising zcytor17 receptor by secretion trap as described below.

[0394] A. COS Cell Transfections

[0395] The COS cell transfection is performed as follows: Mix about 800 ng of zcytor17lig cDNA and 5 μl Lipofectamine™ in 92 μl serum free DMEM media (55 mg sodium pyruvate, 146 mg L-glutamine, 5 mg transferrin, 2.5 mg insulin, 1 μg selenium and 5 mg fetuin in 500 ml DMEM), incubate at room temperature for 30 minutes and then add 400 μl serum free DMEM media. Add this 500 μl mixture onto 1.5×10⁵ COS cells/well plated on 12-well tissue culture plate and incubate for 5 hours at 37° C. Add 500 μl 20% FBS DMEM media (100 ml FBS, 55 mg sodium pyruvate and 146 mg L-glutamine in 500 ml DMEM) and incubate overnight.

[0396] B. Secretion Trap Assay

[0397] The secretion trap is performed as follows: Media is rinsed off cells with PBS and then fixed for 15 minutes with 1.8% Formaldehyde in PBS. Cells are then washed with TNT (0.1M Tris-HCL, 0.15M NaCl, and 0.05% Tween-20 in H₂O), and permeated with 0.1% Triton-X in PBS for 15 minutes, and again washed with TNT. Cells are blocked for 1 hour with TNB (0.1M Tris-HCL, 0.15M NaCl and 0.5% Blocking Reagent (NEN Renaissance TSA-Direct Kit) in H₂O), and washed again with TNT. If using the biotinylated receptor protein, the cells are blocked for 15 minute incubations with Avidin and then Biotin (Vector Labs) washing in-between with TNT. Depending on which soluble receptor is used, the cells are incubated for 1 hour in TNB with: (A) 1-3 μg/ml zcytor17 soluble receptor zcytor17-Fc4 fusion protein (Example 10); (B) 1-3 μg/ml zcytor17/OSMRbeta soluble receptor protein; (C) 1-3 μg/ml zcytor17/WSX-1 soluble receptor protein; or (D) 1-3 μg/ml zcytor17/OSMR WSX-1 soluble receptor protein. Cells are then washed with TNT. Depending on which soluble receptor is used (e.g., if labeled with an Fc4 tag (SEQ ID NO: 37), C-terminal FLAG tag (SEQ ID NO: 36), or CEE tag (SEQ ID NO: 32; SEQ ID NO: 35)), cells are incubated for another hour with: (A) 1:200 diluted goat-anti-human Ig-HRP (Fc specific); (B) 1:1000 diluted M2-HRP; (C) 1:1000 diluted anti-GluGlu antibody-HRP; or (D) 1:300 diluted streptavidin-HRP (NEN kit) in TNB, for example. Again cells are washed with TNT.

[0398] Positive binding is detected with fluorescein tyramide reagent diluted 1:50 in dilution buffer (NEN kit) and incubated for 4-6 minutes, and washed with TNT. Cells are preserved with Vectashield Mounting Media (Vector Labs Burlingame, Calif.) diluted 1:5 in TNT. Cells are visualized using a FITC filter on fluorescent microscope.

Example 13

[0399] Chromosomal Assignment and Placement of the Gene Sequence for the zcytor17lig

[0400] The zcytor17lig gene sequence was mapped to human chromosome 12 using the commercially available version of the “Stanford G3 Radiation Hybrid Mapping Panel” (Research Genetics, Inc., Huntsville, Ala.). The “Stanford G3 RH Panel” contains DNA from each of 83 radiation hybrid clones of the whole human genome, plus, two control DNAs (the RM donor and the A3 recipient). A publicly available WWW server (e.g., Standford University) allows chromosomal localization of markers and genes.

[0401] For the mapping of the zcytor17lig gene sequence with the “Stanford G3 RH Panel”, 20 μl reactions were set up in a 96-well microtiter plate compatible for PCR (Stratagene, La Jolla, Calif.) and used in a “RoboCycler Gradient 96” thermal cycler (Stratagene). Each of the 95 PCR reactions consisted of 2 μl 10× PCR reaction buffer (Qiagen, Inc., Valencia, Calif.), 1.6 μl dNTPs mix (2.5 mM each, PERKIN-ELMER, Foster City, Calif.), 1 μl sense primer, ZC41,458 (SEQ ID NO: 42), 1 μl antisense primer, ZC41,457 (SEQ ID NO: 43), 2 μl “RediLoad” (Research Genetics, Inc., Huntsville, Ala.), 0.1 μl Qiagen HotStarTaq DNA Polymerase (5 units/μl), 25 ng of DNA from an individual hybrid clone or control and distilled water for a total volume of 20 μl. The reactions were overlaid with an equal amount of mineral oil and sealed. The PCR cycler conditions were as follows: an initial 1 cycle 15 minute denaturation at 95° C., 35 cycles of a 45 second denaturation at 95° C., 1 minute annealing at 53° C. and 1 minute and 15 seconds extension at 72° C., followed by a final 1 cycle extension of 7 minutes at 72° C. The reactions were separated by electrophoresis on a 2% agarose gel (EM Science, Gibbstown, N.J.) and visualized by staining with ethidium bromide.

[0402] The results showed linkage of the zcytor17lig gene sequence to the chromosome 12 marker SHGC-83339 with a LOD score of >11 and at a distance of 17 cR_(—)10000 from the marker. This marker positions zcytor17lig gene in the 12q24.31 chromosomal region.

Example 14

[0403] Identification and Cloning of Murine zcytor17lig

[0404] A. Identification of Full Length Murine zcytor17lig

[0405] Using the human zcytor17lig peptide sequence (SEQ ID NO: 2) to query an in house DNA database, a murine cDNA, Genbank Accession No. AK005939, was identified as a potential partial sequence for the murine zcytor17lig. The AK005939 cDNA sequence was used to query a database containing murine genomic fragments. A genomic contig of the murine zcytor17lig was assembled (SEQ ID NO: 76). Prediction of coding potential on this genomic fragment with the program Genscan revealed a likely cDNA sequence, with the same gene structure as the human zcytor17lig. A murine cDNA sequence is represented in SEQ ID NO: 10, and corresponding polypeptide sequence is shown in SEQ ID NO: 11.

[0406] B. Cloning of Mouse zcytor17lig From a Mouse testis cDNA Library by PCR

[0407] Based on the genomic sequence (SEQ ID NO: 76), two PCR primers were designed and used to identify a cDNA source of mouse zcytor17lig by PCR. These Primers ZC41498 (SEQ ID NO: 86) and ZC41496 (SEQ ID NO: 87) were designed to the putative 5′ and 3′ untranslated regions of the mouse sequences (SEQ ID NO:76 and SEQ ID NO: 10). Several cDNA sources were screened by PCR, including Marathon-ready cDNAs (Clontech) and aliquots of locally made cDNA libraries. Products were visualized on 1% agarose gels. Bands of the expected size were observed in reactions utilizing a mouse testis cDNA library template. These PCR reactions were successfully performed in approximately 50 μl volumes with or without 10% DMSO, using pfu turbo polymerase (Stratagene) according to the manufacturer's recommendations; with an additional application of a wax hot-start employing hot start 50s (Molecular Bioproducts, Inc. San Diego, Calif.). PCR thermocycling was performed with a single cycle of 94° C. for 4 min; followed by 40 cycles of 94° C.: 30 seconds, 48° C.: 30 seconds, 72° C.: 50 seconds; with additional final 72° C. extension for 7 minutes. The two PCR reactions were pooled and purified using low melt agarose and Gelase agarose digesting enzyme (Epicenter, Inc. Madison, Wis.) according to the manufacturer's recommendations.

[0408] DNA sequence determination of these PCR products revealed a murine zcytor17 cDNA sequence (SEQ ID NO: 90) which comprised an ORF identical to SEQ ID NO: 10, confirming that SEQ ID NO: 10 encoded the mouse zcytor17lig polypeptide. PCR primers, ZC41583 (SEQ ID NO: 88) and ZC41584 (SEQ ID NO: 89), were then used to add FseI and AscI restriction sites and a partial Kozak sequence to the mcytor17lig open reading frame and termination codon (SEQ ID NO: 92). A Robocycler 40 thermocycler (Stratagene) was used to run a temperature gradient of annealing temperatures and cycling as follows. Pfu turbo polymerase (Stratagene) was applied as described above, but only in 10% DMSO. Cycling was performed with a single cycle of 94° C. for 4 min; followed by 20 cycles of 94° C.: 30 seconds, 65° C. to 51° C. gradient: 30 seconds, 72° C.: 1 minute; and a single 72° C. extension for 7 minutes. The template for this second thermocycling reaction was 1 μl of the initial gel-purified mcytor17lig PCR product, above. Resulting PCR product from the three lowest temperature reactions were pooled and gel purified using the Gelase (Epicenter) method described above. This purified mzcytor17lig was digested with FseI and AscI and ligated into a pZP7X vector modified to have FseI and AscI sites in its cloning site. Plasmid pZP7X is a mammalian expression vector containing an expression cassette having the mouse metallothionein-1 (MT-1) promoter, multiple restriction sites for insertion of coding sequences, and a human growth hormone terminator. The plasmid also has an E. coli origin of replication, a mammalian selective marker expression unit having an SV40 promoter, enhancer and origin of replication, a DHFR gene, and the SV40 terminator. The cloned murine cDNA sequence is represented in SEQ ID NO: 90, and corresponding polypeptide sequence is shown in SEQ ID NO: 91 (which is identical to SEQ ID NO: 11).

Example 15

[0409] Isolation of Mouse zcytor17lig cDNA Clone From an Activated Mouse Spleen library

[0410] A. Murine Primary Source Used to Isolate Mouse zcytor17lig

[0411] Mouse spleens from Balb/C mice, are collected and mashed between frosted-end slides to create a cell suspension. The isolated primary mouse cell yield is expected to be about 6.4×10⁸ cells prior to selection described below.

[0412] The spleen cells are suspended in 9.6 ml MACS buffer (PBS, 0.5% EDTA, 2 mM EDTA). 1.6 ml of cell suspension is removed and 0.4 ml CD90 (Thy1.2) microbeads (Miltenyi Biotec) added. The mixture is incubated for 15 min. at 4° C. These cells labeled with CD90 beads are washed with 30 ml MACS buffer, and then resuspended in 2 ml MACS buffer.

[0413] A VS+ column (Miltenyi) is prepared according to the manufacturer's instructions. The VS+ column is then placed in a VarioMACS™ magnetic field (Miltenyi). The column is equilibrated with 5 ml MACS buffer. The isolated primary mouse cells are then applied to the column. The CD90 negative cells are allowed to pass through. The column is rinsed with 9 ml (3×3 ml) MACS buffer. The column is then removed from the magnet and placed over a 15 ml falcon tube. CD90+ cells are eluted by adding 5 ml MACS buffer to the column and bound cells flushed out using the plunger provided by the manufacturer. The incubation of the cells with the CD90 magnetic beads, washes, and VS+ column steps (incubation through elution) above are repeated once more. The resulting CD90+ fractions from the 2 column separations are pooled. The yield of CD90+ selected mouse spleen cells are expected to be about 1×10⁸ total cells.

[0414] A sample of the pooled CD90+ selected mouse cells is removed for staining and sorting on a fluorescent antibody cell sorter (FACS) to assess their purity. A PE-conjugated hamster anti-mouse CD3ε antibody (PharMingen) is used for staining and sorting the CD90+ selected cells. The mouse CD90+ selected cells should be about 93% CD3+ cells, suggesting the cells are 93% T-cells.

[0415] The murine CD90+ selected cells are activated by incubating 3×10⁶ cells/ml in RPMI+5% FBS+PMA 10 ng/ml and Ionomycin 0.5 μg/ml (Calbiochem) for overnight at 37° C. The supernatant from these activated CD90+ selected mouse cells is tested for zcytor17lig activity as described below. Moreover, the activated CD90+ selected mouse cells are used to prepare a cDNA library, as described in Example 16, below.

Example 16

[0416] Cloning of Mouse zcytor17lig From a Mouse CD90+ Selected Cell Library

[0417] Screening of a primary mouse activated CD90+ selected cell cDNA library can reveal isolated cDNA that is a novel member of the four-helix bundle cytokine family that would encode the mouse ortholog of the human zcytor17lig. The cDNA is identified by hybridization screening.

[0418] A. The Vector for CD90+ Selected Library Construction

[0419] The vector, pZP7N is used for CD3+ selected library construction (See Example 6A)

[0420] B. Preparation of Primary Mouse Activated CD90+ Selected Cell cDNA Library

[0421] Approximately 1.5×10⁸ primary mouse CD90+ selected cells stimulated in ionomycin/PMA (Example 15) are isolated by centrifugation. Total RNA is isolated from the cell pellet, and converted to double stranded cDNA as described in Example 6B. This DNA is subsequently transfected into BHK cells, as described in Example 6B, and proliferation is assessed using an “Alamar blue” fluorescence assay (Example 2B).

[0422] For the purpose of screening the library by secretion trap cloning, a complex, amplified form of the library is needed to transfect COS-7 cells. 4.8 million clones are plated on 110 15 cm LB-agar plates supplemented with 100 μg/ml ampicillin, 10 μg/ml methicillin. After growing the plates overnight at 37° C. the bacteria are harvested by scraping and pelleted. Plasmid DNA is extracted from the pelleted bacteria using a Nucleobond-giga™ (Clonetech) following the manufacturer's instructions. This plasmid is then used to transfect COS-7 cells on slides and screened using the secretion trap technique described below (Example 17).

[0423] C. Screening the Activated Mouse cDNA Library

[0424] Approximately 5×10⁵ clones are plated on 10 LB/Amp Maxi plates. The colonies are lifted, denatured, neutralized, and cross-linked using the standard procedure (Sambrook, J. et al. supra.). Fifty nanograms of the 300 bp 5′ RACE PCR fragment (Example 14) is labeled with ³²P using Prime-Itr RmT random primer labeling kit (Stratagene). The 10 filters are hybridized with this labeled probe at 65° C. overnight using ExpressHyb™ Hybridization Solution (Clontech). The filters are then washed sequentially at 60° C. for 1 hour three times with 0.2×SSC (30 mM NaCl, 3 mM sodium citrate, pH 7.0), 0.1% SDS; and then at 65° C. for 1 hour. The filters are exposed at −80° C. overnight, and the X-ray film are developed. Agar plugs containing the positive colonies are pulled, and the clones plated on 10-cm LB/Amp plates. The colonies are then filter-lifted and hybridized again following the same procedure described above. Single DNA clones are isolated and sequenced using standard methods, to identify the mouse cDNA.

Example 17

[0425] Mouse zcytor17lig Does Not Bind to Human zcytor17 Soluble Receptor in Secretion Trap Assay

[0426] The DNA for mouse clone mzcytor17lig/pZP7 was transfected into COS cells, and the binding of zcytor17 comprising soluble receptors (human zcytor17 soluble receptor zcytor17-Fc4 (Example 10), or soluble receptor heterodimers (zcytor17/WSX-1 or BaF3/zcytor17/OSMRbeta), to the transfected COS cells were tested by a secretion trap assay (Example 12). The assay confirmed that the mouse zcytor17lig does not bind to human zcytor17 soluble receptor.

[0427] The COS cell transfection was performed as per Example 12 using about 0.7 μg mouse zcytor17lig cDNA (Example 16) in 3 μl.

[0428] The secretion trap was performed as per example 12 using, for example, 1 μg/ml zcytor17 soluble receptor Fc4 fusion protein (Example 10) (or zcytor17 comprising soluble receptor heterodimers as described herein) in TNB, and 1:200 diluted goat-anti-human Ig-HRP (Fc specific) in TNB for the detectable antibody. Positive binding of the soluble human zcytor17 receptor to the prepared fixed cells was not detected with fluorescein tyramide reagent as per Example 12. Cells were preserved and visualized according to Example 12.

[0429] Results indicated that the mouse zcytor17lig does not bind to human zcytor17 soluble receptor (or zcytor17 comprising soluble receptor heterodimers as described herein).

Example 18

[0430] Expression of Mouse zcytor17lig in Mammalian Cells

[0431] Mammalian Expression of Mouse zcytor17lig

[0432] BHK 570 cells (ATCC No: CRL-10314) were plated in 10 cm tissue culture dishes and allowed to grow to approximately 20% confluence overnight at 37° C., 5% CO₂, in DMEM/FBS media (DMEM, Gibco/BRL High Glucose media; Gibco BRL, Gaithersburg, Md.), 5% fetal bovine serum (Hyclone, Logan, Utah), 1 mM L-glutamine (JRH Biosciences, Lenexa, Kans.), 1 mM sodium pyruvate (Gibco BRL). The cells were then transfected with the plasmid mzcytor17lig/pZP7X (Example 14) using a mammalian stable Lipofectamine (GibcoBRL) transfection kit according to the manufacturer's instructions.

[0433] One day after transfection, the cells were split 1:10 and 1:20 into the selection media (DMEM/FBS media with the addition of 1 μM methotrexate (Sigma Chemical Co., St. Louis, Mo.)) in 150 mm plates. The media on the cells was replaced with fresh selection media at day 5 post-transfection. Approximately 10 days post-transfection, methotrexate resistant colonies were trypsinized and the cells pooled and plated into large-scale culture flasks. Once the cells were grown to approximately 90% confluence, they were rinsed with PBS three times, and cultured with serum-free ESTEP2 media (DMEM (Gibco BRL), 0.11 g/l Na Pyruvate, 3.7 g/l NaHCO₃, 2.5 mg/l insulin, 5 mg/l transferrin, pH7.0) conditioned media. The conditioned media was collected three days later, and put into a BaF3 proliferation assay using Alamar Blue, described in Example 19 below.

Example 19

[0434] Mouse zcytor17lig Does Not Activate Human zcytor17 Receptor in BaF3 Assay Using Alamar Blue

[0435] Proliferation of BaF3/zcytor17, BaF3/zcytor17/OSMRbeta and BaF3/zcytor17/WSX-1 cells (Example 4, and 5B) was assessed using serum-free conditioned media from BHK cells expressing mouse zcytor17lig (Example 18). BaF3/Zcytor17, BaF3/zcytor17/OSMRbeta and BaF3/zcytor17/WSX-1 cells were spun down, washed and plated in mIL-3 free media as described in Example 5B. Conditioned media from BHK cells expressing mouse zcytor17lig (Example 18) was diluted with mIL-3 free media to 50%, 25%, 12.5%, 6.25%, 3.125%, 1.5%, 0.75% and 0.375% concentrations. The proliferation assay was performed as per Example 5B. The results of this assay were negative, indicating that mouse zcytor17lig does not activate human zcytor17, zcytor17/OSMRbeta, or zcytor17/WSX-1 receptor complexes.

[0436] Human zcytor17lig Activates Human, zcytor17/OSMRbeta Receptor, in luciferase Assay

[0437] A. Construction of BaF3/KZ134/zcytor17 Cell Line

[0438] The KZ134 plasmid was constructed with complementary oligonucleotides ZC12,749 (SEQ ID NO: 44) and ZC12,748 (SEQ ID NO: 45) that contain STAT transcription factor binding elements from 4 genes, which includes a modified c-fos Sis inducible element (m67SIE, or hSIE) (Sadowski, H. et al., Science 261:1739-1744, 1993), the p21 SIE1 from the p21 WAF1 gene (Chin, Y. et al., Science 272:719-722, 1996), the mammary gland response element of the β-casein gene (Schmitt-Ney, M. et al., Mol. Cell. Biol. 11:3745-3755, 1991), and a STAT inducible element of the Fcg RI gene, (Seidel, H. et al., Proc. Natl. Acad. Sci. 92:3041-3045, 1995). These oligonucleotides contain Asp718-XhoI compatible ends and were ligated, using standard methods, into a recipient firefly luciferase reporter vector with a c-fos promoter (Poulsen, L. K. et al., J. Biol. Chem. 273:6229-6232, 1998) digested with the same enzymes and containing a neomycin selectable marker. The KZ134 plasmid was used to stably transfect BaF3 cells, using standard transfection and selection methods, to make the BaF3/KZ134 cell line.

[0439] A stable BaF3/KZ134 indicator cell line, expressing the full-length zcytor17 receptor or zcytor17/OSMRbeta receptor was constructed as per Example 4. Clones were diluted, plated and selected using standard techniques. Clones were screened by luciferase assay (see Example 20B, below) using the human zcytor17lig conditioned media or purified zcytor17lig protein (see Example 35, below) as an inducer. Clones with the highest luciferase response (via STAT luciferase) and the lowest background were selected. Stable transfectant cell lines were selected. The cell lines were called BaF3/KZ134/zcytor17 or BaF3/KZ134/zcytor17/OSMRbeta depending on the receptors transfected into the cell line.

[0440] Similarly, BHK cell lines were also constructed using the method described herein, and were used in luciferase assays described herein. The cell lines were called BHK/KZ134/zcytor17 or BHK/KZ134/zcytor17/OSMRbeta depending on the receptors transfected into the cell line.

[0441] B. Human zcytor17lig Activates Human zcytor17 Receptor in BaF3/KZ134/zcytor17/OSMRbeta or BHK/KZ134/zcytor17/OSMRbeta luciferase Assay

[0442] BaF3/KZ134/zcytor17 and BaF3/KZ134/zcytor17/OSMRbeta cells were spun down and washed in mIL-3 free media. The cells were spun and washed 3 times to ensure removal of mIL-3. Cells were then counted in a hemacytometer. Cells were plated in a 96-well format at about 30,000 cells per well in a volume of 100 μl per well using the mIL-3 free media. The same procedure was used for untransfected BaF3/KZ134 cells for use as a control in the subsequent assay. BHK/KZ134/zcytor17 or BHK/KZ134/zcytor17/OSMRbeta cells were plated in a 96-well format at 15,000 cells per well in 100 μl media. Parental BHK/KZ134 cells were used as a control.

[0443] STAT activation of the BaF3/KZ134/Zcytor17, BaF3/KZ134/zcytor17/OSMRbeta, BHK/KZ134/zcytor17, or BHK/KZ134/zcytor17/OSMRbeta cells was assessed using (1) conditioned media from BHK570 cells transfected with the human zcytor17lig (Example 7), (2) conditioned media from BHK570 cells transfected with the mouse zcytor17lig (Example 18), (3) purified human zcytor17lig (Example 35), or (4) mIL-3 free media to measure media-only control response. Conditioned media was diluted with RPMI mIL-3 free media to 50%, 25%, 12.5%, 6.25%, 3.125%, 1.5%, 0.75% and 0.375% concentrations. Purified human zcytor17lig was diluted to a concentration of 1200, 600, 300, 150, 75, 37.5, 18.75, or 9.4 pM. 100 μl of the diluted conditioned media or protein was added to the BaF3/KZ134/Zcytor17, BaF3/KZ134/zcytor17/OSMRbeta, BHK/KZ134/zcytor17, or BHK/KZ134/zcytor17/OSMRbeta cells. The assay using the conditioned media was done in parallel on untransfected BaF3/KZ134 or BHK/KZ134 cells as a control. The total assay volume was 200 μl. The assay plates were incubated at 37° C., 5% CO₂ for 24 hours at which time the BaF3 cells were pelleted by centrifugation at 2000 rpm for 10 min., and the media was aspirated and 25 μl of lysis buffer (Promega) was added. For the BHK cell lines, the centrifugation step was not necessary as the cells are adherant. After 10 minutes at room temperature, the plates were measured for activation of the STAT reporter construct by reading them on a luminometer (Labsystems Luminoskan, model RS) which added 40 μl of luciferase assay substrate (Promega) at a five second integration.

[0444] The results of this assay confirmed that the STAT reporter response of the BaF3/KZ134/zcytor17/OSMRbeta and BHK/KZ134/zcytor17/OSMRbeta cells to the human zcytor17lig when compared to either the BaF3/KZ134/zcytor17 cells, the BHK/KZ134/zcytor17 cells or the untransfected BaF3/KZ134 or BHK/KZ134 control cells, showed that the response was mediated through the zcytor17/OSMRbeta receptors. The results also showed that the mouse zcytor17lig does not activate the STAT reporter assay through the human receptor complex.

[0445] Mouse zcytor17lig is Active in Mouse Bone Marrow Assay

[0446] A. Isolation of Non-Adherent Low Density Marrow Cells:

[0447] Fresh mouse femur aspirate (marrow) is obtained from 6-10 week old male Balb/C or C57BL/6 mice. The marrow is then washed with RPMI+10% FBS (JRH, Lenexa Kans.; Hyclone, Logan Utah) and suspended in RPMI+10% FBS as a whole marrow cell suspension. The whole marrow cell suspension is then subjected to a density gradient (Nycoprep, 1.077, Animal; Gibco BRL) to enrich for low density, mostly mononuclear, cells as follows: The whole marrow cell suspension (About 8 ml) is carefully pipeted on top of about 5 ml Nycoprep gradient solution in a 15 ml conical tube, and then centrifuged at 600× g for 20 minutes. The interface layer, containing the low density mononuclear cells, is then removed, washed with excess RPMI+10% FBS, and pelleted by centrifugation at 400× g for 5-10 minutes. This pellet is resuspended in RPMI+10% FBS and plated in a T-75 flask at approximately 10⁶ cells/ml, and incubated at 37° C. 5% CO₂ for approximately 2 hours. The resulting cells in suspension are Non-Adherent Low Density (NA LD) Marrow Cells.

[0448] B. 96-Well Assay

[0449] NA LD Mouse Marrow Cells are plated at 25,000 to 45,000 cells/well in 96 well tissue culture plates in RPMI+10% FBS+1 ng/mL mouse Stem Cell Factor (mSCF) (R&D Systems, Minneapolis, Minn.), plus 5% conditioned medium from one of the following: (1) BHK 570 cells expressing mouse zcytor17lig (Example 18), (2) BHK 570 cells expressing human zcytor17lig (Example 7), or (3) control BHK 570 cells containing vector and not expressing either Ligand. These cells are then subjected to a variety of cytokine treatments to test for expansion or differentiation of hematopoietic cells from the marrow. For testing, the plated NA LD mouse marrow cells are subjected to human Interleukin-15 (hIL-15) (R&D Systems), or one of a panel of other cytokines (R&D Systems). Serial dilution of hIl-15, or the other cytokines, are tested, with 2-fold serial dilution from about 50 ng/ml down to about 0.5 ng/ml concentration. After 8 to 12 days the 96-well assays are scored for cell proliferation by Alamar blue assay as described in Example 5B.

[0450] C. Results From the 96-Well NA LD Mouse Marrow Assay

[0451] Conditioned media from the BHK cells expressing both mouse and human zcytor17lig can promote the expansion of a population of hematopoietic cells either alone or in synergy with other cytokines in the NA LD mouse marrow in comparison to control BHK conditioned medium. The population hematopoietic cells expanded by the mouse zcytor17lig with or without other cytokines, and those hematopoietic cells expanded by the human zcytor17lig with or without other cytokines, are further propagated in cell culture. These hematopoietic cells are stained with a Phycoerythrin labeled anti-Pan NK cell antibody (PharMingen) and subjected to flow cytometry analysis, which demonstrated that the expanded cells stained positively for this natural killer (NK) cell marker. Similarly, other specific hematopoietic cell markers can be used to determine expansion of, for example, CD4+ or CD8+ T-cells, other T-cell populations, B-cells, and other immune cell markers.

[0452] The same 96-well assay is run, using fresh human marrow cells bought from Poietic Technologies, Gaithersburg, Md. Again, a positive result shows that zcytor17lig alone or in synergy with other cytokines, the mouse and human zcytor17lig can expand a hematopoietic cell population that is stained positively for specific cell markers as disclosed above.

[0453] Constructs for Generating zcytor17lig Transgenic Mice

[0454] A. Construct for Expressing Human zcytor17lig From the MT-1 Promoter

[0455] Oligonucleotides are designed to generate a PCR fragment containing a consensus Kozak sequence and the human zcytor17lig coding region. These oligonucleotides are designed with an FseI site at the 5′ end and an AscI site at the 3′ end to facilitate cloning into (a) pMT12-8, our standard transgenic vector, or (b) pKFO51, a lymphoid-specific transgenic vector (Example 22B).

[0456] PCR reactions are carried out with about 200 ng human zcytor17lig template (SEQ ID NO: 1) and oligonucleotides designed to amplify the full-length or active portion of the zcytor17lig. PCR reaction conditions are determined using methods known in the art. PCR products are separated by agarose gel electrophoresis and purified using a QiaQuick™ (Qiagen) gel extraction kit. The isolated, correct sized DNA fragment is digested with FseI and AscI (Boerhinger-Mannheim), ethanol precipitated and ligated into pMT12-8 previously digested with FseI and AscI. The pMT12-8 plasmid, designed for expressing a gene of interest in liver and other tissues in transgenic mice, contains an expression cassette flanked by 10 kb of MT-1 5′ DNA and 7 kb of MT-1 3′ DNA. The expression cassette comprises the MT-1 promoter, the rat insulin II intron, a polylinker for the insertion of the desired clone, and the human growth hormone (hGH) poly A sequence.

[0457] About one microliter of each ligation reaction is electroporated into DH10B ElectroMax™ competent cells (GIBCO BRL, Gaithersburg, Md.) according to manufacturer's direction and plated onto LB plates containing 100 μg/ml ampicillin, and incubated overnight. Colonies are picked and grown in LB media containing 100 μg/ml ampicillin. Miniprep DNA is prepared from the picked clones and screened for the human zcytor17lig insert by restriction digestion with EcoRI alone, or FseI and AscI combined, and subsequent agarose gel electrophoresis. Maxipreps of the correct pMT-human zcytor17lig are performed. A SalI fragment containing with 5′ and 3′ flanking sequences, the MT-1 promoter, the rat insulin II intron, human zcytor17lig cDNA and the hGH poly A sequence is prepared to be used for microinjection into fertilized murine oocytes. Microinjection and production of transgenic mice are produced as described in Hogan, B. et al. Manipulating the Mouse Embryo, 2^(nd) ed., Cold Spring Harbor Laboratory Press, NY, 1994.

[0458] B. Construct for Expressing Human zcytor17lig From the lymphoid-Specific EμLCK Promoter

[0459] Oligonucleotides are designed to generate a PCR fragment containing a consensus Kozak sequence and the human zcytor17lig coding region. These oligonucleotides are designed with an FseI site at the 5′ end and an AscI site at the 3′ end to facilitate cloning into pKFO51, a lymphoid-specific transgenic vector.

[0460] PCR reactions are carried out with about 200 ng human zcytor17lig template (SEQ ID NO: 1) and oligonucleotides designed to amplify the full-length or active portion of the zcytor17lig. A PCR reaction is performed using methods known in the art. The isolated, correct sized DNA fragment is digested with FseI and AscI (Boerhinger-Mannheim), ethanol precipitated and ligated into pKFO51 previously digested with FseI and AscI. The pKFO51 transgenic vector is derived from p1026X (Iritani, B. M., et al., EMBO J. 16:7019-31, 1997) and contains the T cell-specific lck proximal promoter, the B/T cell-specific immunoglobulin μ heavy chain enhancer, a polylinker for the insertion of the desired clone, and a mutated hGH gene that encodes an inactive growth hormone protein (providing 3′ introns and a polyadenylation signal).

[0461] About one microliter of each ligation reaction is electroporated, plated, clones picked and screened for the human zcytor17lig insert by restriction digestion as described above. A correct clone of pKFO51-zcytor17lig is verified by sequencing, and a maxiprep of this clone is performed. A NotI fragment, containing the lck proximal promoter and immunoglobulin μ enhancer (EμLCK), zcytor17lig cDNA, and the mutated hGH gene is prepared to be used for microinjection into fertilized murine oocytes.

[0462] C. Construct for Expressing Mouse zcytor17lig From the EF1alpha Promoter

[0463] Primers ZC41,498 (SEQ ID NO: 86) and ZC41,496 (SEQ ID NO: 87) were used to PCR a mouse testis cDNA library template. These PCR reactions were successfully performed in approximately 50 μl volumes with or without 10% DMSO, using pfu turbo polymerase (Stratagene) according to the manufacturer's recommendations; with an additional application of a wax hot-start employing hot start 50s (Molecular Bioproducts, Inc. San Diego, Calif.). PCR thermocycling was performed with a single cycle of 94° C. for 4 min; followed by 40 cycles of 94° C.: 30 seconds, 48° C.: 30 seconds, 72° C.: 50 seconds; with additional final 72° C. extension for 7 minutes. The two PCR reactions were pooled and purified using low melt agarose and Gelase agarose digesting enzyme (Epicenter, Inc. Madison, Wis.) according to the manufacturer's recommendations.

[0464] DNA sequenced PCR products revealed a murine zcytor17 cDNA sequence (SEQ ID NO: 90) which comprised an ORF identical to SEQ ID NO: 10, confirming that SEQ ID NO: 10 encoded the mouse zcytor17lig polypeptide. PCR primers, ZC41583 (SEQ ID NO: 88) and ZC41584 (SEQ ID NO: 89), were then used to add FseI and AscI restriction sites and a partial Kozak sequence to the mcytor17lig open reading frame and termination codon (SEQ ID NO: 92). A Robocycler 40 thermocycler (Stratagene) was used to run a temperature gradient of annealing temperatures and cycling as follows. Pfu turbo polymerase (Stratagene) was applied as described above, but only in 10% DMSO. Cycling was performed with a single cycle of 94° C. for 4 min; followed by 20 cycles of 94° C.: 30 seconds, 65° C. to 51° C. gradient: 30 seconds, 72° C.: 1 minute; and a single 72° C. extension for 7 minutes. The template for this second thermocycling reaction was 1 μl of the initial gel-purified mcytor17lig PCR product, above. Resulting PCR product from the three lowest temperature reactions were pooled and gel purified using the Gelase (Epicenter) method described above. This purified fragment was then digested with FseI and AscI and ligated into a pZP7X vector modified to have FseI and AscI sites in its cloning site. This was sent to sequencing to confirm the correct sequence. The cloned murine cDNA sequence is represented in SEQ ID NO: 90, and corresponding polypeptide sequence is shown in SEQ ID NO: 91 (which is identical to SEQ ID NO: 11).

[0465] The isolated, correct sized DNA fragment digested with FseI and AscI (Boerhinger-Mannheim) was subcloned into a plasmid containing EF1alpha promoter previously digested with FseI and AscI. Maxipreps of the correct EF1alpha mouse zcytor17lig were performed. The expression cassette contains the EF1alpha promoter (with a deleted FseI site), the EF1alpha intron, SUR IRES like site to facilitate expression, a polylinker flanked with rat insulin II sites on the 5′ end which adds FseI PmeI AscI sites for insertion of the desired clone, and the human growth hormone (hGH) poly A sequence. A 7.5 kb NotI fragment containing the EF1alpha promoter expression cassette and mouse zcytor17lig was prepared to be used for microinjection into fertilized murine oocytes. The EF1alpha plsdmid was obtained from Louis-Marie of the Laboratoire de Differenciation Cellulaire, as described in Taboit-Dameron et al., 1999, Transgenic Research 8:223-235.

[0466] D. Construct for Expressing Mouse zcytor17lig From the lymphoid-Specific EμLCK Promoter

[0467] Oligonucleotides were designed to generate a PCR fragment containing a consensus Kozak sequence and the mouse zcytor17lig coding region. These oligonucleotides were designed with an FseI site at the 5′ end and an AscI site at the 3′ end to facilitate cloning into pKFO51 (see Example 22B, above).

[0468] The isolated, correct sized zcytor17lig DNA fragment used in EF1alpha constructs, digested with FseI and AscI (Boerhinger-Mannheim), was subcloned into a plasmid containing pKFO51, a lymphoid-specific transgenic vector. The pKFO51 transgenic vector is derived from p1026X (Iritani, B. M., et al., EMBO J. 16:7019-31, 1997) and contains the T cell-specific lck proximal promoter, the B/T cell-specific immunoglobulin μ heavy chain enhancer, a polylinker for the insertion of the desired clone, and a mutated hGH gene that encodes an inactive growth hormone protein (providing 3′ introns and a polyadenylation signal). A 6.5 kb NotI fragment, containing the lck proximal promoter and immunoglobulin μ enhancer (EμLCK), mouse zcytor17lig cDNA, and the mutated hGH gene was prepared to be used for microinjection into fertilized murine oocytes (Example 41).

Example 23

[0469] Construction of Mammalian Expression Vectors That Express zcytor17lig-CEE

[0470] A. Construction of zCytor17Lig-CEE/pZMP21

[0471] An expression plasmid containing all or part of a polynucleotide encoding human zCytor17lig was constructed via homologous recombination. The plasmid was called zCytor17Lig-CEE/pZMP21.

[0472] The construction of zCytor17Lig-CEE/pZMP21 was accomplished by generating a zCytor17Lig-CEE fragment (SEQ ID NO: 95) using PCR amplification. The DNA template used for the production of the zCytor17Lig-CEE fragment was zCytor17Lig/pZP7nx. The primers used for the production of the zCytor17Lig-CEE fragment were: (1) ZC41607 (SEQ ID NO: 97) (sense sequence), which includes from the 5′ to the 3′ end: 28bp of the vector flanking sequence (5′ of the insert) and 21 bp corresponding to the 5′ sequence of zCytor17Lig; and (2) ZC41605 (SEQ ID NO: 98) (anti-sense sequence), which includes from the 5′ to the 3′ end: 37 bp of the vector flanking sequence (3′ of the insert), 3 bp of the stop codon, 21 bp encoding a C-terminal EE tag, and 21 bp corresponding to the 3′ end of zCytor17Lig sequence. The fragment resulting from the above PCR amplification is a copy of the template zCytor17Lig with the addition of a C-terminal EE tag, yielding a final product zCytor17Li g-CEE.

[0473] PCR reactions were run as follows: To a 100 μl final volume was added: 10 μl of 10× Taq Polymerase Reaction Buffer with 15 mM MgCl (Gibco), 1 μl of Taq DNA Polymerase (5 units/μl, Gibco), 3 μl of 10 mM dNTPs, 78 μl dH2O, 3 μl of a 20 pmol/μl stock of primer ZC41607 (SEQ ID NO: 97) 3 μl of a 20 pmol/μl stock of primer ZC41605 (SEQ ID NO: 98), and 2 μl of a 0.13 μg/μl stock of zCytor17lig template DNA. A volume equal to 50 μl of mineral oil was added to the mixture. The reaction was heated to 94° C. for 5 minutes, followed by 35 cycles at 94° C. for 1 minute; 55° C. for 2 minutes; 72° C. for 3 minutes; followed by a 10 minute extension at 72° C. and held at 4° C. until the reaction was collected.

[0474] The plasmid pZMP21 was restriction digested with BglII enzyme, cleaned with a QiaQuick PCR Purification Kit (Qiagen) using a microcentrifuge protocol, and used for recombination with the PCR fragment. Plasmid pZMP21 was constructed from pZMP20 which was constructed from pZP9 (deposited at the American Type Culture Collection, 10801 University Boulevard, Manassas, Va. 20110-2209, and is designated No. 98668) with the yeast genetic elements taken from pRS316 (deposited at the American Type Culture Collection, 10801 University Boulevard, Manassas, Va. 20110-2209, and designated No. 77145), an IRES element from poliovirus, and the extracellular domain of CD8, truncated at the carboxyl terminal end of the transmembrane domain. PZMP21 is a mammalian expression vector containing an expression cassette having the MPSV promoter, immunoglobulin signal peptide intron, multiple restriction sites for insertion of coding sequences, a stop codon and a human growth hormone terminator. The plasmid also has an E. coli origin of replication, a mammalian selectable marker expression unit having an SV40 promoter, enhancer and origin of replication, a DHFR gene, the SV40 terminator, as well as the URA3 and CEN-ARS sequences required for selection and replication in S. cerevisiae.

[0475] Fifty microliters of competent yeast cells (S. cerevisiae) were independently combined with 100 ng of cut plasmid, 5 μl of previously described PCR mixture, and transferred to a 0.2 cm electroporation cuvette. The yeast/DNA mixture was electropulsed at 0.75 kV (5 kV/cm), ∞ ohms, 25 μF. Each cuvette had 600 μl of 1.2 M sorbitol added, and the yeast was plated in one 100 μl aliquot and one 300 μl aliquot onto two URA-D plates and incubated at 30° C. After about 72 hours, the Ura+ yeast transformants from a single plate were resuspended in 1 ml H₂O and spun briefly to pellet the yeast cells. The cell pellet was resuspended in 500 μl of lysis buffer (2% Triton X-100, 1% SDS, 100 mM NaCl, 10 mM Tris, pH 8.0, 1 mM EDTA). The 500 μl of the lysis mixture was added to an Eppendorf tube containing 300 μl acid washed 600 μm glass beads and 300 μl phenol-chloroform, vortexed for 1 minute intervals two or three times, followed by a 5 minute spin in a Eppendorf centrifuge at maximum speed. Three hundred microliters of the aqueous phase was transferred to a fresh tube, and the DNA precipitated with 600 μl 100% ethanol (EtOH), followed by centrifugation for 10 minutes at 4° C. The DNA pellet was then washed with 500 μl 70% EtOH, followed by centrifugation for 1 minute at 4° C. The DNA pellet was resuspended in 30 μl H₂O.

[0476] Transformation of electrocompetent E. coli cells (MC1061) was done with 5 μl of the yeast DNA prep and 50 μl of MC1061 cells. The cells were electropulsed at 2.0 kV, 25 μF and 400 ohms(Ω). Following electroporation, 600 μl SOC (2% Bacto′ Tryptone (Difco, Detroit, Mich.), 0.5% yeast extract (Difco), 10 mM NaCl, 2.5 mM KCl, 10 mM MgCl₂, 10 mM MgSO₄, 20 mM glucose) was added. The electroporated E.coli cells were plated in a 200 μl and a 50 μl aliquot on two LB AMP plates (LB broth (Lennox), 1.8% Bacto Agar (Difco), 100 mg/L Ampicillin). The plates were incubated upside down for about 24 hours at 37° C. Three Ampicillin-resistant colonies were selected at random and submitted for sequence analysis of the insert. Large scale plasmid DNA was isolated from a sequence-confirmed clone using the Qiagen Maxi kit (Qiagen) according to manufacturer's instructions.

[0477] B. Mammalian Expression of Human zcytor17lig

[0478] Full-length zCytor17Lig protein was produced in BHK cells transfected with zCytor17Lig-CEE/pZMP21 (Example 23A). BHK 570 cells (ATCC CRL-10314) were plated in T75 tissue culture flasks and allowed to grow to approximately 50 to 70% confluence at 37° C., 5% CO₂, in growth media (SL7V4, 5% FBS, 1% pen/strep). The cells were then transfected with zCytor17Lig-CEE/pZMP21 by liposome-mediated transfection (using Lipofectamine™; Life Technologies), in serum free (SF) media (SL7V4). The plasmid (16 μg) was diluted into 1.5 ml tubes to a total final volume of 640 μl with SF media. Thirty-five microliters of the lipid mixture was mixed with 605 μl of SF medium, and the resulting mixture was allowed to incubate approximately 15 minutes at room temperature. Five milliliters of SF media was then added to the DNA:lipid mixture. The cells were rinsed once with 10 ml of PBS, the PBS was decanted, and the DNA:lipid mixture was added. The cells are incubated at 37° C. for five hours, then 15 ml of media (SL7V4, 5% FBS, 1% pen/strep) was added to each plate. The plates were incubated at 37° C. overnight, and the DNA:lipid media mixture was replaced with selection media (SL7V4, 5% FBS, 1% pen/strep, 1 μM methotrexate) the next day. Approximately 10 days post-transfection, methotrexate-resistant colonies from the T75 transfection flask were trypsinized, and the cells were pooled and plated into a T-162 flask and transferred to large-scale culture.

[0479] Expression of zcytor17 Soluble Receptor in E. coli

[0480] A. Construction of Expression Vector pCMH01 That Expresses huzcytor17/MBP-6H Fusion polypeptide

[0481] An expression plasmid containing a polynucleotide encoding a zcytor17 soluble receptor fused C-terminally to maltose binding protein (MBP) was constructed via homologous recombination. The fusion polypeptide contains an N-terminal approximately 388 amino acid MBP portion fused to any of the zcytor17 soluble receptors described herein. A fragment of zcytor17 cDNA (SEQ ID NO: 4) was isolated using PCR as described herein. Two primers were used in the production of the zcytor17 fragment in a standard PCR reaction: (1) one containing about 40 bp of the vector flanking sequence and about 25 bp corresponding to the amino terminus of the zcytor17, and (2) another containing about 40 bp of the 3′ end corresponding to the flanking vector sequence and about 25 bp corresponding to the carboxyl terminus of the zcytor17. Two μl of the 100 μl PCR reaction was run on a 1.0% agarose gel with 1× TBE buffer for analysis, and the expected approximately fragment was seen. The remaining PCR reaction was combined with the second PCR tube and precipitated with 400 μl of absolute ethanol. The precipitated DNA used for recombining into the Sma1 cut recipient vector pTAP170 to produce the construct encoding the MBP-zcytor17 fusion, as described below.

[0482] Plasmid pTAP170 was derived from the plasmids pRS316 and pMAL-c2. The plasmid pRS316 is a Saccharomyces cerevisiae shuttle vector (Hieter P. and Sikorski, R., Genetics 122:19-27, 1989). pMAL-C2 (NEB) is an E. coli expression plasmid. It carries the tac promoter driving MalE (gene encoding MBP) followed by a His tag, a thrombin cleavage site, a cloning site, and the rrnB terminator. The vector pTAP170 was constructed using yeast homologous recombination. 100 ng of EcoR1 cut pMAL-c2 was recombined with 1 μg Pvu1 cut pRS316, 1 μg linker, and 1 μg Sca1/EcoR1 cut pRS316. The linker consisted of oligos zc19,372 (SEQ ID NO: 172) (100 pmole): zc19,351 (SEQ ID NO: 173) (1 pmole): zc19,352 (SEQ ID NO: 174) (1 pmole), and zc19,371 (SEQ ID NO: 175) (100 pmole) combined in a PCR reaction. Conditions were as follows: 10 cycles of 94° C. for 30 seconds, 50° C. for 30 seconds, and 72° C. for 30 seconds; followed by 4° C. soak. PCR products were concentrated via 100% ethanol precipitation.

[0483] One hundred microliters of competent yeast cells (S. cerevisiae) were combined with 10 μl of a mixture containing approximately 1 μg of the human zcytor17 insert, and 100 ng of SmaI digested pTAP170 vector, and transferred to a 0.2 cm electroporation cuvette. The yeast/DNA mixture was electropulsed at 0.75 kV (5 kV/cm), infinite ohms, 25 μF. To each cuvette was added 600 μl of 1.2 M sorbitol. The yeast was then plated in two 300 μl aliquots onto two −URA D plates and incubated at 30° C.

[0484] After about 48 hours, the Ura+ yeast transformants from a single plate were picked, DNA was isolated, and transformed into electrocompetent E. coli cells (e.g., MC1061, Casadaban et. al. J. Mol. Biol. 138, 179-207), and plated on MM/CA +KAN 25 μg/L plates (Pryor and Leiting, Protein Expression and Purification 10:309-319, 1997) using standard procedures. Cells were grown in MM/CA with 25 μg/ml Kanomyacin for two hours, shaking, at 37° C. One ml of the culture was induced with 1 mM IPTG. Two to four hours later the 250 μl of each culture was mixed with 250 μl acid washed glass beads and 250 μl Thorner buffer with 5% βME and dye (8M urea, 100 mM Tris pH7.0, 10% glycerol, 2 mM EDTA, 5% SDS). Samples were vortexed for one minute and heated to 65° C. for 10 minutes. 20 μl were loaded per lane on a 4%-12% PAGE gel (NOVEX). Gels were run in 1XMES buffer. The positive clones were designated pCMH01 and subjected to sequence analysis.

[0485] One microliter of sequencing DNA was used to transform strain BL21. The cells were electropulsed at 2.0 kV, 25 μF and 400 ohms. Following electroporation, 0.6 ml MM/CA with 25 μg/L Kanomyacin. Cells were grown in MM/CA and induced with ITPG as described above. The positive clones were used to grow up for protein purification of the huzcytor17/MBP-6H fusion protein using standard techniques.

[0486] B. Purification of huzcytor17/MBP-6H Soluble Receptor From E. coli Fermentation

[0487] Unless otherwise noted, all operations were carried out at 4° C. The following procedure was used for the purification of recombinant huzcytor17/MBP-6H soluble receptor polypeptide. E. coli cells containing the pCMH01 construct and expressing huzcytor17/MBP-6H soluble receptor polypeptide were constructed using standard molecular biology methods and cultured in SuperBroth II (12 g/L Casien, 24 g/L Yeast Extract, 11.4 g/L di-potassium phosphate, 1.7 g/L Mono-potassium phosphate; Becton Dickenson, Cockeysville, Md.). The resulting cells were harvested and frozen in 0.5% glycerol. Twenty grams of the frozen cells were used for protein purification.

[0488] Thawed cells were resuspended in 500 mL Amylose Equilibration buffer (20 mM Tris, 100 mM NaCl, pH 8.0). A French Press cell breaking system (Constant Systems Ltd., Warwick, UK) with a temperature setting of −7° C. to −10° C. and 30K PSI was used to lyse the cells. The resuspended cells were checked for breakage by A₆₀₀ readings before and after cycling through the French Press. The lysed cell suspension was pelleted at 10,000G for 30 minutes. Supernatant was harvested from the debris pellet for protein purification.

[0489] Twenty-five milliliters of Amylose resin (New England Biolabs, Beverly, Mass.) was poured into a Bio-Rad, 2.5 cm D×10 cm H glass column. The column was packed and equilibrated by gravity with 10 column volumes (CVs) of Amylose Equilibration buffer. The harvested cell supernatant was batch loaded to the Amylose resin, overnight with rocking. The loaded resin was returned to the glass column, washed with 10 CVs Amylose Equilibration buffer, and eluted by gravity with −2 CVs Amylose Elution buffer (Amylose Equilibration buffer, 10 mM Maltose, Fluka Biochemical, Switzerland). Ten 5 ml fractions were collected over the elution profile and assayed for absorbance at 280 and 320 nM. The Amylose resin was regenerated with 1 CV of distilled H₂O, 5 CVs of 0.1% (w/v) SDS (Sigma), 5 CVs of distilled H₂O, 5 CVs of Amylose Equilibration buffer, and finally 1 CV of Amylose Storage buffer (Amylose Equilibration buffer, 0.02% (w/v) Sodium Azide). The regenerated resin was stored at 4° C.

[0490] Elution profile fractions of interest were pooled and dialyzed in a 10K dialysis chamber (Slide-A-Lyzer, Pierce Immunochemical) against 4 changes of 4L PBS pH 7.4 (Sigma) over an 8 hour time period. Following dialysis, the material harvested represented the purified huzcytor17/MBP-6H polypeptide. The purified huzcytor17/MBP-6H polypeptide was filter sterilized and analyzed via SDS-PAGE Coomassie staining for an appropriate molecular weight product. The concentration of the huzcytor17/MBP-6H polypeptide was determined by BCA analysis to be 0.76 mg/ml.

[0491] Purified huzcytor17/MBP-6H polypeptide was appropriately formulated for the immunizaton of rabbits and sent to R & R Research and Development (Stanwood, Wash.) for polyclonal antibody production (Example 25, below).

[0492] Human zcytor17 Receptor Polyclonal Antibody

[0493] A. Preparation and Purification

[0494] Polyclonal antibodies were prepared by immunizing 2 female New Zealand white rabbits with the purified recombinant protein huzcytor17/MBP-6H (Example 24). The rabbits were each given an initial intraperitoneal (IP) injection of 200 μg of purified protein in Complete Freund's Adjuvant followed by booster IP injections of 100 μg protein in Incomplete Freund's Adjuvant every three weeks. Seven to ten days after the administration of the second booster injection (3 total injections), the animals were bled and the serum was collected. The animals were then boosted and bled every three weeks.

[0495] The huzcytor17/MBP-6H specific rabbit serum was pre-adsorbed of anti-MBP antibodies using a CNBr-SEPHAROSE 4B protein column (Pharmacia LKB) that was prepared using 10 mg of non-specific purified recombinant MBP-fusion protein per gram of CNBr-SEPHAROSE. The huzcytor17/MBP-6H-specific polyclonal antibodies were affinity purified from the pre-adsorbed rabbit serum using a CNBr-SEPHAROSE 4B protein column (Pharmacia LKB) that was prepared using 10 mg of the specific antigen purified recombinant protein huzcytor17/MBP-6H. Following purification, the polyclonal antibodies were dialyzed with 4 changes of 20 times the antibody volume of PBS over a time period of at least 8 hours. Human zcytor17-specific antibodies were characterized by ELISA using 500 ng/ml of the purified recombinant protein huzcytor17/MBP-6H as antibody target. The lower limit of detection (LLD) of the rabbit anti-huzcytor17/MBP-6H affinity purified antibody is 500 pg/ml on its specific purified recombinant antigen huzcytor17/MBP-6H.

[0496] B. SDS-PAGE and Western Blotting Analysis of Rabbit Anti-Human ZcytoR17 MBP-6H Antibody

[0497] Rabbit anti-human ZcytoR17 MBP-6H antibody was tested by SDS-PAGE (NuPage 4-12%, Invitrogen, Carlsbad, Calif.) with coomassie staining method and Western blotting using goat anti-rabbit IgG-HRP. Either purified protein (200-25 ng) or conditioned media containing zcytor17 was electrophoresed using an Invitrogen Novex's Xcell II mini-cell, and transferred to nitrocellulose (0.2 mm; Invitrogen, Carlsbad, Calif.) at room temperature using Novex's Xcell blot module with stirring according to directions provided in the instrument manual. The transfer was run at 300 mA for one hour in a buffer containing 25 mM Tris base, 200 mM glycine, and 20% methanol. The filter was then blocked with Western A buffer (in house, 50 mM Tris, pH 7.4, 5 mM EDTA, pH 8.0, 0.05% Igepal CA-630, 150 mM NaCl, and 0.25% gelatin) overnight with gentle rocking at 4° C. The nitrocellulose was quickly rinsed, then the rabbit anti-human zcytoR17 MBP-6H (1:1000) was added in Western A buffer. The blot was incubated for 1.5 hours at room temperature with gentle rocking. The blot was rinsed 3 times for 5 minutes each in Western A, then goat anti-rabbit IgG HRP antibody (1:1000) was added in Western A buffer. The blot was incubated for 1.25 hours at room temperature with gentle rocking. The blot was rinsed 3 times for 5 minutes each in Western A, then quickly rinsed in H₂O. The blot was developed using commercially available chemiluminescent substrate reagents (ECLWestern blotting detection reagents 1 and 2 mixed 1:1; reagents obtained from Amersham Pharmacia Biotech, Buckinghamshire, England) and the blot was exposed to X-ray film for up to 15 minutes.

[0498] The rabbit anti-human zcytoR17 MBP-6H was able to detect human zcytor17 present in conditioned media as well as zcytoR17 purified protein as a band at 120 kDa under reducing conditions.

[0499] Tissue Distribution of Mouse zcytor17 in Tissue Panels Using PCR

[0500] A panel of cDNAs from murine tissues was screened for mouse zcytor17 expression using PCR. The panel was made in-house and contained 94 marathon cDNA and cDNA samples from various normal and cancerous murine tissues and cell lines are shown in Table 6, below. The cDNAs came from in-house libraries or marathon cDNAs from in-house RNA preps, Clontech RNA, or Invitrogen RNA. The mouse marathon cDNAs were made using the marathon-Ready™ kit (Clontech, Palo Alto, Calif.) and QC tested with mouse transferrin receptor primers ZC10,651 (SEQ ID NO: 46) and ZC10,565 (SEQ ID NO: 47) and then diluted based on the intensity of the transferrin band. To assure quality of the amplified library samples in the panel, three tests for quality control (QC) were run: (1) To assess the RNA quality used for the libraries, the in-house cDNAs were tested for average insert size by PCR with vector oligos that were specific for the vector sequences for an individual cDNA library; (2) Standardization of the concentration of the cDNA in panel samples was achieved using standard PCR methods to amplify full length alpha tubulin or G3PDH cDNA using a 5′ vector oligo: ZC14,063 (SEQ ID NO: 48) and 3′ alpha tubulin specific oligo primer ZC17,574 (SEQ ID NO: 49) or 3′ G3PDH specific oligo primer ZC17,600 (SEQ ID NO: 50); and (3) a sample was sent to sequencing to check for possible ribosomal or mitochondrial DNA contamination. The panel was set up in a 96-well format that included a mouse genomic DNA (Clontech, Palo Alto, Calif.) positive control sample. Each well contained approximately 0.2-100 pg/μl of cDNA. The PCR was set up using oligos ZC38,065 (SEQ ID NO: 51) and ZC38,068 (SEQ ID NO: 52), TaKaRa Ex Taq™ (TAKARA Shuzo Co LTD, Biomedicals Group, Japan), and Rediload dye (Research Genetics, Inc., Huntsville, Ala.). The amplification was carried out as follows: 1 cycle at 94° C. for 5 minutes; 5 cycles of 94° C. for 30 seconds, 68° C. for 30 seconds; 35 cycles of 94° C. for 30 seconds, 56° C. for 30 seconds and 72° C. for 30 seconds, followed by 1 cycle at 72° C. for 5 minutes. About 10 μl of the PCR reaction product was subjected to standard Agarose gel electrophoresis using a 4% agarose gel. The correct predicted DNA fragment size was observed in brain, CD90+ cells, dendritic, embryo, MEWt#2, Tuvak-prostate cell line, salivary gland, skin and testis.

[0501] The DNA fragment for skin and testis were excised and purified using a Gel Extraction Kit (Qiagen, Chatsworth, Calif.) according to manufacturer's instructions. Fragments were confirmed by sequencing to show that they were indeed mouse zcytor17.

[0502] Human Zcytor17 Expression in Various Tissues Using Real-Time

[0503] Quantitative RT/PCR

[0504] A. Primers and Probes for Human Zcytor17, OSMRbeta and Zcytor17lig for Conventional and Quantitative RT-PCR

[0505] Real-time quantitative RT-PCR using the ABI PRISM 7900 Sequence Detection System (PE Applied Biosystems, Inc., Foster City, Calif.) has been previously described (See, Held, C. A. et al., Genome Research 6:986-994, 1996; Gibson, U. E. M. et al., Genome Research 6:995-1001, 1996; Sundaresan, S. et al., Endocrinology 139:4756-4764, 1998). This method incorporates use of a gene specific probe containing both reporter and quencher fluorescent dyes. When the probe is intact the reporter dye emission is negated due to the close proximity of the quencher dye. During PCR extension using additional gene-specific forward and reverse primers, the probe is cleaved by 5′ nuclease activity of Taq polymerase which releases the reporter dye from the probe resulting in an increase in fluorescent emission.

[0506] The primers and probes used for real-time quantitative RT-PCR analyses of human Zcytor17, OSMRbeta and Zcytor17ligand expression were designed using the primer design software Primer Express™ (PE Applied Biosystems, Foster City, Calif.). Primers for human Zcytor17 were designed spanning an intron-exon junction to eliminate possible amplification of genomic DNA. The forward primer, ZC37,877 (SEQ ID NO: 53) and the reverse primer, ZC37,876 (SEQ ID NO: 54) were used in a PCR reaction at a 200 nM concentration to synthesize a 73 bp product. The corresponding Zcytor17 TaqMan® probe, designated ZC37,776 (SEQ ID NO: 55) was synthesized and labeled by PE Applied Biosystems and used in each PCR reaction at a concentration of 200 nM. The ZC37,776 (SEQ ID NO: 55) probe was labeled at the 5′end with a reporter fluorescent dye (6-carboxy-fluorescein) (FAM) (PE Applied Biosystems) and at the 3′ end with a fluorescent quencher dye (6-carboxy-tetramethyl-rhodamine) (TAMRA) (Epoch Biosciences, Bothell, Wash.).

[0507] Primers for human OSMRbeta were designed spanning an intron-exon junction to eliminate possible amplification of genomic DNA. The forward primer, ZC43,891 (SEQ ID NO: 137) and the reverse primer, ZC43,900 (SEQ ID NO: 138) were used in a PCR reaction (below) at a 200 nM concentration. The corresponding OSMRbeta TaqMan® probe, designated ZC43,896 (SEQ ID NO: 139) was synthesized and labeled by PE Applied Biosystems and used in each PCR reaction at a concentration of 200 nM. The ZC43,896 (SEQ ID NO: 139) probe was labeled at the 5′end with a reporter fluorescent dye (6-carboxy-fluorescein) (FAM) (PE Applied Biosystems) and at the 3′ end with a non-fluorescent quencher dye (ECLIPSE) (Epoch Biosciences).

[0508] Primers for human Zcytor17ligand were designed spanning an intron-exon junction to eliminate possible amplification of genomic DNA. The forward primer, ZC43,280 (SEQ ID NO: 140) and the reverse primer, ZC43,281 (SEQ ID NO: 141) were used in a PCR reaction (below) at about 200 nM concentration. The corresponding Zcytor17ligand TaqMan™ probe, designated ZC43,275 (SEQ ID NO: 142) was synthesized and labeled by PE Applied Biosystems and used in each PCR reaction at a concentration of 200 nM. The ZC43,275 (SEQ ID NO: 142) probe was labeled at the 5′end with a reporter fluorescent dye (6-carboxy-fluorescein) (FAM) (PE Applied Biosystems) and at the 3′ end with a non-fluorescent quencher dye (ECLIPSE) (Epoch Biosciences).

[0509] As a control to test the integrity and quality of RNA samples tested, all RNA samples were screened for either rRNA or GUS using primer and probe sets either ordered from PE Applied Biosystems (rRNA kit) or designed in-house (GUS). The rRNA kit contained the forward primer (SEQ II) NO: 56), the rRNA reverse primer (SEQ ID NO: 57), and the rRNA TaqMan® probe (SEQ ID NO: 58). The rRNA probe was labeled at the 5′end with a reporter fluorescent dye VIC (PE Applied Biosystems) and at the 3′ end with the quencher fluorescent dye TAMRA (PE Applied Biosystems). The GUS primers and probe were generated in-house and used in each PCR reaction at 200 nM and 100 nM, respectively. The forward primer was ZC40,574 (SEQ ID NO: 143) and the reverse primer was ZC40,575 (SEQ ID NO: 144). The GUS probe ZC43,017 (SEQ ID NO: 145) was labeled at the 5′end with a reporter fluorescent dye (Yakima-Yellow) (Epoch Biosciences) and at the 3′end with a non-fluorescent quencher dye (ECLIPSE) (Epoch Biosciences). The rRNA and GUS results also serve as an endogenous control and allow for the normalization of the Zcytor17 mRNA expression results seen in the test samples.

[0510] For conventional non-quantitative RT-PCR, primers were designed using the primer design software Primer Express™ (PE Applied Biosystems, Foster City, Calif.). The human zcytor17 primers generate an approximately 1000 base pair product and are as follows: forward primer ZC28,917 (SEQ ID NO: 83), and reverse primer ZC28,480 (SEQ ID NO: 146). The human OSMRbeta primers generate a 202 base pair product and are as follows: forward primer ZC41,653(SEQ ID NO: 147) and reverse primer ZC41,655 (SEQ ID NO: 148). The human Zcytor17ligand primers generate a 305 base pair product and are as follows: forward primer ZC41,703 (SEQ ID NO: 149) and reverse primer ZC41,704 (SEQ ID NO: 150).

[0511] B. Primers and Probes for Murine Zcytor17, OSMRbeta and Zcytor17ligand for Conventional and Quantitative RT-PCR

[0512] The primers and probes used for real-time quantitative RT-PCR analyses of murine Zcytor17, OSMRbeta and Zcytor17lig expression were designed using the primer design software Primer Express™ (PE Applied Biosystems, Foster City, Calif.). Primers for murine Zcytor17 were designed spanning an intron-exon junction to eliminate possible amplification of genomic DNA. The forward primer, ZC43,272 (SEQ ID NO: 151) and the reverse primer, ZC43,273 (SEQ ID NO: 152) were used in the PCR reactions (below) at 300 nM concentration. The corresponding Zcytor17 TaqMan® probe, designated ZC43,478 (SEQ ID NO: 153) was synthesized and labeled is by PE Applied Biosystems. The ZC43,478 (SEQ ID NO: 153) probe was labeled at the 5′end with a reporter fluorescent dye (6-carboxy-fluorescein) (FAM) (PE Applied Biosystems) and at the 3′ end with a quencher fluorescent dye (6-carboxy-tetramethyl- rhodamine) (TAMRA) (PE Applied Biosystems). The ZC43,478 (SEQ ID NO: 153) probe was used in the PCR reactions at a concentration of 100 nM.

[0513] Primers for murine Zcytor17ligand were designed spanning an intron-exon junction to eliminate possible amplification of genomic DNA. The forward primer, ZC43,278 (SEQ ID NO: 154) and the reverse primer, ZC43,279 (SEQ ID NO: 155) were used in the PCR reactions at 500 nM concentration. The corresponding Zcytor17ligand TaqMan® probe, designated ZC43,276 (SEQ ID NO: 156) was synthesized and labeled by PE Applied Biosystems. The ZC43,478 (SEQ ID NO: 153) probe was labeled at the 5′end with a reporter fluorescent dye (6-carboxy-fluorescein) (FAM) (PE Applied Biosystems) and at the 3′ end with a non-fluorescent quencher dye (ECLIPSE) (Epoch Biosciences). The ZC43,276 (SEQ ID NO: 156) probe was used in the PCR reactions (below) at a concentration of 200 nM.

[0514] Primers for murine OSMRbeta were designed spanning an intron-exon junction to eliminate possible amplification of genomic DNA. The forward primer, ZC43,045 (SEQ ID NO: 157) and the reverse primer, ZC43,046 (SEQ ID NO: 158) were used in the PCR reactions at a 300 nM concentration. The corresponding OSMRbeta TaqMan® probe, designated ZC43,141(SEQ ID NO: 159) was synthesized and labeled by Epoch Biosciences. The ZC43,141 (SEQ ID NO: 159) probe was labeled at the 5′end with a reporter fluorescent dye (6-carboxy-fluorescein) (FAM) (PE Applied Biosystems) and at the 3′ end with a non-fluorescent quencher dye (ECLIPSE) (Epoch Biosciences). The ZC43,141 (SEQ ID NO: 159) probe was used in the PCR reactions (below) at a concentration of 100 nM.

[0515] As a control to test the integrity and quality of RNA samples tested, all RNA samples were screened for either murine GUS or transferrin receptor using primers and probes designed using the primer design program Primer Express™ (PE Applied Biosystems Inc., Foster City, Calif.). The murine GUS primers are as follows: forward primer, ZC43,004 (SEQ ID NO: 160), reverse primer, ZC43,005 (SEQ ID NO: 161), and TaqMan® probe ZC43,018 (SEQ ID NO: 162). The murine GUS probe ZC43,018 (SEQ ID NO: 162) was labeled at the 5′end with a reporter fluorescent dye Yakima-Yellow (Epoch Biosciences) and at the 3′ end with the non-fluorescent quencher dye ECLIPSE (Epoch Biosciences). The murine GUS primers were used in the PCR reactions at 300 nM and the probe, ZC43,018 (SEQ ID NO: 162), was used at 100 nM. In some cases murine Transferrin Receptor was used instead of GUS as the endogenous control. The transferrin receptor forward primer, ZC40,269 (SEQ ID NO: 163) and the reverse primer, ZC40,268 (SEQ ID NO: 164) were used at 300 nM. The transferrin receptor probe, ZC40,298 (SEQ ID NO: 165) was used in PCR at 100 nM and was labeled at the 5′end with a reporter fluorescent dye VIC (PE Applied Biosystems) and at the 3′end with a fluorescent quencher dye (TAMRA) (PE Applied Biosystems). The murine GUS and transferrin receptor results also serve as an endogenous control and allow for the normalization of the Zcytor17, OSMRbeta and Zcytor17ligand mRNA expression results seen in the test samples.

[0516] For conventional semi-quantitative RT-PCR, primers were designed using the primer design software Primer Express™ (PE Applied Biosystems).

[0517] C. Protocols for Realtime Quantitative RT-PCR and Conventional Semi-Quantitative RT-PCR

[0518] Relative levels of Zcytor17, OSMRbeta and Zcytor17ligand mRNA were determined by analyzing total RNA samples using the one-step RT-PCR method (PE Applied Biosystems). Total RNA from Zcytor17- and OSMRbeta-transfected BAF cells (human) or BHK cells (murine) was isolated by standard methods and used to generate a standard curve used for quantitation of Zcytor17 and OSMRbeta. The curve consisted of 10-fold serial dilutions ranging from 100-0.01 ng/μl with each standard curve point analyzed in triplicate. Similarly, for Zcytor17ligand, activated CD4+ T cell RNA (previously shown to make Zcytor17ligand) was used to generate a standard curve in the same 100-0.01 ng/μl range. Total RNA from human or murine cells was analyzed in triplicate for either human or murine Zcytor17, OSMRbeta and Zcytor17ligand transcript levels and for one of the following endogenous control genes: rRNA, GUS or transferrin receptor. In a total volume of 10 μl, each RNA sample was subjected to a One-Step RT-PCR reaction containing: approximately 50-100 ng of total RNA in a preformulated 2× master mix containing an internal control dye (ROX)(carboxy-x-rhodamine) and Thermo-Start® DNA Polymerase (Abgene, Surrey, UK); appropriate primers for the gene of interest (see parts A and B of current example); the appropriate probe (see parts A and B for concentration); Superscript® reverse transcriptase (50 U/μl) (PE Applied Biosystems), and an appropriate volume of RNase-free water. PCR thermal cycling conditions were as follows: an initial reverse transcription (RT) step of one cycle at 48° C. for 30 minutes; followed by a Thermo-Start® enzyme activation step of one cycle at 95° C. for 10 minutes; followed by 40 cycles of amplification at 95° C. for 15 seconds and 60° C. for 1 minute. Relative Zcytor17, OSMRbeta and Zcytor17ligand RNA levels were determined by using the Standard Curve Method as described by the manufacturer, PE Biosystems (User Bulletin #2: ABI Prism 7700 Sequence Detection System, Relative Quantitation of Gene Expression, Dec. 11, 1997). The rRNA, GUS or Transferrin Receptor measurements were used to normalize the levels of the gene of interest.

[0519] The semi-quantitative RT-PCR reactions used the ‘Superscript One-Step RT-PCR System with Platinum Taq’ (Invitrogen, Carlsbad, Calif.). Each 25 μl reaction consisted of the following: 12.5 μl of 2×Reaction Buffer, 0.5 μl (20 pmol/μl) of forward primer, 0.5 μl (20 pmol/μl) of reverse primer, 0.4 μl RT/Taq polymerase mix, 5.0 μl of Rediload Gel Loading Buffer (Invitrogen), 5.1 μl RNase-free water, and 1.0 μl total RNA (100 ng/μl). The amplification was carried out as follows: one cycle at 45° C. for 30 minutes followed by 35-38 cycles of 94° C., 20 seconds; Variable annealing temp (See Table 7 below), 20 seconds; 72° C., 45 seconds; then ended with a final extension at 72° C. for 5 minutes. Eight to ten microliters of the PCR reaction product was subjected to standard agarose gel electrophoresis using a 2% agarose gel.

[0520] D. Isolation of RNA from Human and Murine PBMC Subsets and Cell Lines

[0521] Blood was drawn from several anonymous donors and peripheral blood mononuclear cells (PBMC) isolated using standard Ficoll gradient methodology. Monocytes were then isolated using the Monocyte Isolation Kit and the Magnetic Cell Separation System (Miltenyi Biotec, Auburn, Calif.). The monocytes were then plated onto ultra-low adherence 24-well plates in endotoxin-free media. They were either unstimulated or treated with recombinant human IFNg (R&D Systems Inc.) at 10 ng/ml. Cells were collected at 24 and 48 hours. In similar manner, CD4+ and CD8+ T cells were isolated from PBMC's using the anti-CD4 or anti-CD8 magnetic beads from Miltenyi Biotec. Cells were then activated for 4 or 16 hours in tissue culture plates coated with 0.5 μg/ml anti-CD3 antibodies in media containing 5 μg/ml anti-CD28 antibodies. NK cells were also isolated from PBMC's using Miltenyi's anti-CD56 coated magnetic beads. Some of the NK cells were collected at time zero for RNA and the others were plated in media containing Phorbol Myristate Acetate (PMA) (5 ng/ml) and ionomycin (0.5 μg/ml) for 24 hours. Additionally, several human monocyte-like cell lines, U937, THP-1 and HL-60, were collected in either their resting or activated states. U937 cells were activated overnight with PMA (10 ng/ml). HL-60's were activated overnight with PMA (10 ng/ml) or for 72 and 96 hours with IFNg (10 ng/ml) to drive them down a monocytic pathway. THP-1 cells were activated overnight with a combination of LPS (10 ng/ml) and IFNg (10 ng/ml). RNA was prepared from all primary cells using the RNeasy Midiprep™ Kit (Qiagen, Valencia, Calif.) as per manufacturer's instructions. Carryover DNA was removed using the DNA-Free™ kit (Ambion, Inc., Austin, Tex.). RNA concentration was determined using standard spectrophotometry and RNA quality determined using the Bioanalyzer 2100 (Agilent Technologies, Palo Alto, Calif.).

[0522] Murine T Cell RNA was collected using a variety of methods well-known in the art. Primary splenic CD4+ and CD8+ T cells were isolated from the spleens of C57B1/6 mice using antibody-coated magnetic beads and the Magnetic Cell Separation System from Miltenyi Biotec. The CD4+ and CD8+T cells were then activated by culturing the cells in 24-well plates coated with anti-CD3 antibodies (500 ng/ml) in media containing anti-CD28 antibodies at 5 μg/ml. Cells were harvested for RNA at 0, 4 and 16 hours. Similarly, CD4+ T cells were isolated and then skewed towards a Th1 or Th2 phenotype using the following protocol. Since C57B1/6 T cells are already skewed in the Th1 direction, all that was required was to activate for 6 hours with 0.5 μg/ml PMA and 10 ng/ml ionomycin. ‘Th2’ skewing was obtained by plating naïve CD4+ T cells with 2.5 μg/ml anti-CD28, 10 ng/ml mIL-2 (R&D Systems Inc.) and 25 ng/ml mIL-4 (R&D Systems) into plates coated with 0.5 μg/ml anti-CD3. After 2 days in culture, cells were resuspended in media containing 10 ng/ml mIL-2 (R&D Systems) and 25 ng/ml mIL-4. Cells were cultured for an additional three days then activated with PMA and ionomycin for 6 hours.

[0523] One additional set of Th1 and Th2 skewed T cells was derived using the T Cell Receptor Transgenic DO11.10 T cell line. All cells were plated into anti-CD3 and anti-CD28 coated plates. The ‘Th1’ cells were plated in media containing mIL-12 (1 ng/ml) and anti-IL-4 (10 μg/ml). The ‘Th2’ cells were plated in media containing mIL-4 (10 ng/ml) and anti-IFNg (10 μg/ml). After 24 hours, all cultures were given mIL-2 (10 ng/ml). After two more days, the media on the cells was changed and new media containing the aforementioned cytokines was added and cells were cultured an additional 4 days before being harvested.

[0524] All of the murine T cell RNA was prepared using the RNeasy Midiprep™ Kit (Qiagen) and contaminating DNA was removed using the DNA-free™ kit from Ambion.

[0525] E. Isolation of RNA from the Murine Models of Pancreatitis and Irritable Bowel Disease

[0526] To induce a condition similar to human Irritable Bowel Disease (IBD), the hybrid mouse strain C57B16/129S6F1 was used. Mice were divided into 4 groups with an average size of six mice per group. Group 1 was given no Dextran Sulfate Sodium (DSS) and was sacrificed on day 14. Group 2 received 2% DSS for two days prior to being sacrificed. Group 3 received 2% DSS for seven days prior to sacrifice. Group 4 received 2% DSS for seven days then allowed to recover for seven days and was sacrificed on day 14. On the day of sacrifice, the distal colon sections were removed and placed in RNAlater™ (Ambion). The colon sections were homogenized using standard techniques and RNA was isolated using the RNeasy Midiprep™ Kit (Qiagen). Contaminating DNA was removed by DNA-free™ (Ambion) treatment as per manufacturer's instructions.

[0527] In a different study, acute pancreatitis was induced in male CD-1 mice by caerulein injection. Mice were divided into three groups (n=8 mice/group). Group 1 animals were given seven i.p. injections (1 injection per hour) with Vehicle (saline), and then sacrificed at 12 and 24 hours following the first injection. Groups 2 and 3 were given seven i.p. injections of caerulein (Sigma) (Catalog#C-9026) at a dose of 50 μg/kg/hr for six hours (1 injection per hour). Group 2 was sacrificed at 12 hrs after the first injection and Group 3 was sacrificed at 24 hrs following the first injection. Pancreases were removed at the time of sacrifice and snap frozen for RNA isolation. Tissues were homogenized and RNA was isolated using the Qiagen RNeasy Midiprep™ Kit.

[0528] In yet another study, murine Zcytor17ligand transgenic mice were generated and observed for phenotypic changes (see Example 41). Piloerection and hair loss was observed in many of the transgenic mice. Four transgenic mice were sacrificed and skin samples from both normal and hairless areas were removed and snap frozen for later RNA isolation. Skin sections from two non-transgenic control mice were collected as well. Skin samples were homogenized and then digested with Proteinase K (Qiagen) (Catalog# 19133) for 20 minutes at 60° C. RNA was then isolated using the Qiagen RNeasy Midiprep™ Kit following manufacturer's instructions. Carryover DNA was removed using DNA-free™ kit from Ambion.

[0529] F. Results of Quantitative and Semi-Quantitative RT-PCR for Human Zcytor17, OSMRbeta and Zcytor17ligand

[0530] Zcytor17 and OSMRbeta expression was examined by quantitative RT-PCR in four sets of primary human monocytes that were either in their resting state or activated with IFNg for 24 or 48 hours. Zcytor17 expression was below detection in the unstimulated cells but increased dramatically after the 24-hour activation with IFNg, and was the highest after 48 hours of activation. In all cases OSMRbeta was below detection. Zcytor17ligand was not tested in these samples.

[0531] In the primary T cells, Zcytor17 was below detection in both the resting CD4+ and CD8+ subsets. After a four-hour activation, however, expression of Zcytor17 went up in both subsets and then decreased to a slightly lower level at the 16 hour time point. OSMRbeta was below detection in these samples. Zcytor17ligand expression was examined using semi-quantitative RT-PCR. No expression was detected in the unstimulated CD4+ and CD8+ T cells. However, after the four hour activation, high levels of Zcytor17ligand were detected. This level dropped somewhat at the 16 hour time point.

[0532] Expression of Zcytor17 was not examined in NK cells. OSMRb was below detection in these samples. Zcytor17ligand expression was below detection in the resting NK cells, however there was a faint signal generated by the activated NK cells suggesting that these cells may make Zcytor17ligand under certain conditions.

[0533] In the human monocyte-like cell lines, U937, THP-1 and HL-60, OSMRbeta expression was below detection in all of the resting and activated samples except for activated THP-1 samples where a faint signal was detected. Zcytor17 expression was high in both the U937 and THP-1 resting cell lines and showed a strong upregulation following activation. Expression in U937's was the highest of any cell type. In the HL-60's, Zcytor17 was expressed at moderate levels in the unstimulated cells and decreased upon stimulation with PMA. However, the expression of Zcytor17 was dramatically upregulated in the HL-60's when stimulated with IFNg for 72 and 96 hours. All of the human expression data is summarized in Table 8 below.

[0534] G. Results of Quantitative and Semi-Quantitative RT-PCR for Murine Zcytor17, OSMRbeta and Zcytor17ligand

[0535] Murine Zcytor17, OSMRbeta and Zcytor17ligand expression levels were examined in several murine T cells populations and the results are summarized in Table 9 below. Murine Zcytor17 expression was tested by semi-quantitative RT-PCR and shown to be at low levels on both resting and activated primary CD4+ T cells. Expression of Zcytor17 was detected on resting CD8+ T cells and then seemed to drop upon activation with anti-CD3 and anti-CD28 antibodies at both the 4- and 16-hour time points. OSMRbeta expression was measured by quantitative RT-PCR and shown to be expressed in resting and activated CD4+ and CD8+ T cells. The expression of OSMRbeta went up after a 4-hour activation and then returned to the unstimulated levels by 16 hours in both the CD4+ and CD8+ T cells. Zcytor17ligand was detected by quantitative RT-PCR and shown to be expressed at very low levels in unstimulated CD4+ T cells. However, following a 4-hour activation, Zcytor17ligand expression was dramatically upregulated and then dropped slightly by the 16-hour time point. In CD8+ T cells, no Zcytor17ligand was detected in the unstimulated cells. There was some Zcytor17ligand expression at the 4-hour time point, but by 16 hours expression levels had dropped back below detection.

[0536] In the DO11.10 T cells, Zcytor17 expression was detected in the naive and Th2 skewed cells, but not in the Th1 skewed cells. OSMRbeta expression was at low levels in the naïve DO11.10 cells. There was a dramatic increase in OSMRbeta expression levels in the Th1 skewed cells and a moderate increase of expression in the Th2-skewed cells. The Zcytor17ligand expression in these cells was shown to be predominantly by the Th2 skewed subset. Low levels were detected in the Th1 subset and no expression was detected in the naive cells. These results are summarized in the Table 9 below.

[0537] In the primary CD4+ T cells that were skewed in either the Th1 or Th2 direction, Zcytol7 wasn't examined. OSMRbeta expression was detected in all three samples with the highest levels found in the Th2 sample. Similar to the DO11.10 results, Zcytor17ligand expression was detected at high levels in the Th2 skewed subset, with a small amount detected in the Th1 subset and levels were below detection in the unstimulated cells. These results are summarized in the Table 9 below. TABLE 9 Murine T Cells Zcytor17 OSMRbeta Zcytor17ligand CD4+ T Cells Unstimulated + + +/− CD4+ T Cells 4 hr Activation + ++ ++ CD4+ T Cells 16 hr + + + Activation CD8+ T Cells Unstimulated + + − CD8+ T Cells 4 hr Activation +/− ++ + CD8+ T Cells 16 hr − + − Activation DO11.10 Naive + + − DO11.10 Th1 − +++ + DO11.10 Th2 + ++ ++ CD4+ T Cells Unstimulated ++ − CD4+ T Cells - Th1 Skewed +++ + CD4+ T Cells - Th2 Skewed ++ +++

[0538] In the Zcytor17ligand transgenic skin samples, Zcytor17, OSMRbeta and Zcytor17ligand expression levels were determined using quantitative RT-PCR. Zcytor17 was shown to be present in all samples at roughly equivalent levels. There were dramatically higher levels of OSMRbeta expression in the non-transgenic control animals than the transgenic samples. Zcytor17ligand expression was below detection in the non-transgenic control animals with moderate to high levels of expression in the transgenic animals. The results are summarized in Table 10 below. TABLE 10 Murine Zcytor17ligand Skin Transgenic Skin Phenotype Zcytor17 OSMRbeta Zcytor17ligand Wild Type Mouse Normal + +++ − Wild Type Mouse Normal + +++ − Transgenic #1 Normal + + + Transgenic #1 Hair Loss + + + Transgenic #2 Normal + + + Transgenic #2 Hair Loss + + + Transgenic #3 Normal + + + Transgenic #3 Hair Loss + + + Transgenic #4 Normal + + +++ Transgenic #4 Hair Loss + + +++

[0539] In a different experiment, Zcytor17, OSMRbeta and Zcytor17ligand expression levels were measured by quantitative RT-PCR in the pancreases of mice subjected to acute pancreatitis. Zcytor17 expression was below detection in all of the samples. OSMRbeta expression was seen at low levels in the normal control samples (Group 1), but showed a strong upregulation at the 12-hour time point (Group 2) and slightly lower levels at the 24-hour time point (Group 3). Zcytor17ligand expression was below detection in the control animals, but showed high levels in both of the caerulein injected groups. The data is summarized in Table 11 below. TABLE 11 Pancreatitis Model Description Zcytor17 OSMRbeta Zcytor17ligand Group 1 Normal Control − + − Group 2 12 hr Post − +++ ++ Injection Group 3 24 hr Post − ++ ++ Injection

[0540] In another experiment, Zcytor17 and OSMRbeta expression levels were examined in the distal colons of mice subjected to DSS treatment. In this murine model of Inflammatory Bowel Disease, expression levels of both genes were determined by quantitative RT-PCR and are summarized in Table 12 below. Zcytor17 expression levels increased with the severity of the disease, with low levels of expression in the Group 1 normal animals and increasing amounts seen Groups 2 and 3. In the Group 4 animals, the Zcytor17 levels had returned to more normal levels. Unlike Zcytor17 expression, OSMRbeta levels were the highest in the control animals and levels actually decreased in all three DSS treated groups.

Example 28

[0541] Human Zcytor17lig Tissue Distribution Expression Based on RT-PCR Analysis of Multiple Tissue First-Strand cDNAs

[0542] Gene expression of the zcytor17lig was examined using commercially available normalized multiple tissue first-strand cDNA panels (OriGene Technologies, Inc. Rockville, Md.; BD Biosciences Clontech, Palo Alto, Calif.). These included the OriGene “Human Tissue Rapid-Scan™ Panel” (Cat. #CHSCA-101, containing 22 different tissues, bone marrow, and plasma blood leucocytes) and the BD Biosciences Clontech “Human Blood Fractions MTC™ Panel” (Cat. #K1428-1, containing 9 different blood fractions).

[0543] PCR reactions were set up using the zcytor17lig specific oligo primers ZC41,458 (SEQ ID NO: 60), and ZC41,457 (SEQ ID NO: 61), which yield a 139 bp product, and ZC41,459 (SEQ ID NO: 62), and ZC41,460 (SEQ ID NO: 63), which yield a 92 bp product, Qiagen HotStarTaq DNA polymerase and buffer (Qiagen, Inc., Valencia, Calif.), dH₂O, and RediLoad dye (Research Genetics, Inc., Huntville, Ala.). The PCR cycler conditions were as follows: an initial 1 cycle 15 minute denaturation at 95° C., 35 cycles of a 45 second denaturation at 95° C., 1 minute annealing at 53° C. or 56° C. and 1 minute and 15 seconds extension at 72° C., followed by a final 1 cycle extension of 7 minutes at 72° C. The reactions were separated by electrophoresis on a 2% agarose gel (EM Science, Gibbstown, N.J.) and visualized by staining with ethidium bromide.

[0544] A DNA fragment of the correct size was observed in the following human adult tissues using the OriGene “Human Tissue Rapid-Scan™ Panel”: testis, plasma blood leucocytes (PBL), and bone marrow.

[0545] A DNA fragment of the correct size was observed in the following human blood fractions using the BD Biosciences Clontech “Human Blood Fractions MTC™ Panel”: activated mononuclear cells (B- & T-cells and monocytes), activated CD8+ cells (T-suppressor/cytotoxic), activated CD4+ cells (T-helper/inducer) and faintly in resting CD8+ cells.

Example 29

[0546] Cloning the Human Oncostatin M Receptor

[0547] The OncostatinM beta receptor (OSMRbeta) is a type I cytokine receptor with structural similarity to EL12R-B2. ZcytoR17 has structural similarity to IL12R-B1. The OSMRbeta and zcytor17 were tested to see whether they could interact as subunits in a cytokine signaling complex, and whether together they could act as a signaling receptor, or soluble receptor antagonist, for zcytor17lig.

[0548] To isolate OSMRbeta, oligonucleotide PCR primers ZC39982 (SEQ ID NO: 64) and ZC39983 (SEQ ID NO: 65) were designed to amplify the full length coding region of the human OncostatinM beta cDNA sequence (SEQ ID NO: 6) (Genbank Accession No. U60805; Mosley B, JBC Volume 271, Number 50, Issue of Dec. 20, 1996 pp. 32635-32643).

[0549] PCR reactions were run on an array of cDNA library templates using a robust polymerase, Advantage II (Clonetech, Palo Alto, Calif.), in order to identify a source of the cDNA. The template DNA used was from amplified cDNA plasmid libraries each containing 5 million independent cDNA clones. Reactions were assembled as per manufacturer's instructions using 400 fmol/μl of each oligonucleotide and 2-20 ng/μl purified plasmid library DNA as template. The cDNA libraries were derived from the following human tissues and cell lines: fetal brain, prostate smooth muscle, bone marrow, RPM11588, thyroid, WI-38, testis, stimulated peripheral blood mononuclear cells, stimulated CD3+ cells, THP-1, activated tonsil, HACAT and fetal liver. Reactions were performed on a thermocycler machine using the following conditions: 30 cycles of 95° C. for 20 seconds, 68° C. for 3 minutes. At the conclusion of 30 cycles an additional single extension cycle of 8 minutes at 68° C. was run. PCR products were visualized by TAE agarose, gel electrophoresis in the presence of ethidium bromide followed by UV illumination. The most abundant product was found to be from a prostate smooth muscle cDNA library. The PCR reaction using prostate smooth muscle template and oligonucleotides ZC39982 (SEQ ID NO: 64) and ZC39983 (SEQ ID NO: 65) was repeated using a less robust but higher fidelity thermostable DNA polymerase “turboPFu”, (Stratagene, La Jolla, Calif.). Thirty amplification cycles were run with the following conditions: denaturing at 94° C., 30 seconds, annealing at 63° C. 45 seconds, extension at 72° C. 3.5 minutes. A single band product was gel purified on a 0.8% TAE, agarose gel.

[0550] This DNA was then amplified again using primers ZC39980 (SEQ ID NO: 66) and ZC39981 (SEQ ID NO: 67) designed to include restriction enzyme recognition sequences to allow the cloning of this cDNA into a mammalian expression vector.

[0551] The PCR reaction was performed using “TurboPfu” and the purified PCR product for 15 cycles of: 95° C. 1 minute, 64° C. 1 minute 20 seconds, 72° C. 4.5 minutes. The PCR reaction was then digested with EcoR1 and Xho1 (Invitrogen, Carlsbad, Calif.) and gel purified as described above. A mammalian expression vector, pZ7NX, was prepared by digesting with EcoR1 and Xho1 and the PCR product was ligated to this vector and electroporated into E. coli DH10b cells. Several bacterial colonies were isolated and sequenced. One clone was correct with the exception of a single non-conservative mutation. In order to change this base to match the expected sequence, an oligonucleotide spanning mutation and a neighboring Pst1 restriction site was used in a PCR reaction with:“TurboPfu” using the pZP7Nx-h. OncostatinM R plasmid previously sequenced as a template. The PCR amplified DNA was digested with Pst1 and Xho1 and cloned back into the pZP7Nx-h OncostatinM R plasmid in place of the Pst1/Xho1 fragment containing the offending mutation. This new plasmid was sequenced over the recently amplified Pst1 to Xho1 region to confirm the correction and make sure no other errors were created in the amplification process. This analysis confirmed sequence that matched the expected sequence over the coding region. The sequence is shown in SEQ ID NO: 6, and corresponding amino acid sequence shown in SEQ ID NO: 7.

[0552] Constructs for Generating a Human Zcytor17/OncostatinM receptor (OSMRbeta) Heterodimer

[0553] A system for construction, expression and purification of such soluble heterodimeric receptors is known in the art, and has been adapted to the receptor pair, human oncostatin M receptor (OSMRbeta) and human zcytor17. For this construct, the polynucleotide for the soluble receptor for OSMRbeta is shown in SEQ ID NO: 68 and corresponding polypeptide is shown in SEQ ID NO: 69; and the polynucleotide for the soluble receptor for human zcytor17 is shown in SEQ ID NO: 70 and corresponding polypeptide is shown in SEQ ID NO: 71.

[0554] To construct a cell line expressing a secreted soluble hzcytor17/human OSMRbeta heterodimer, a construct was made so that the resulting heterodimeric soluble receptor comprises the extracellular domain of human OSMRbeta fused to the heavy chain of IgG gammal (Fc4) (SEQ ID NO: 37) with a Glu-Glu tag (SEQ ID NO: 35) at the C-terminus; while the extracellular domain of zcytoR17 is fused to Fc4 (SEQ ID NO: 37) with a His tag (SEQ ID NO: 72) at the C-terminus. For both of the hzcytor17 and human OSMRbeta arms of the heterodimer a Gly-Ser spacer of 12 amino acids (SEQ ID NO: 73) was engineered between the extracellular portion of the receptor and the N-terminus of Fc4.

[0555] A. Construction of Human Soluble OSMRbeta/Fc4-CEE

[0556] For construction of the human soluble OSMRbeta/Fc4-CEE portion of the heterodimer the extracellular portion of human OSMRbeta was isolated using PCR with oligos ZC14063 (SEQ ID NO: 48) and ZC41557 (SEQ ID NO: 74) under PCR reaction conditions as follows: 30 cycles of 95° C. for 60 sec., 57° C. for 30 sec., and 72° C. for 100 sec.; and 72° C. for 7 min. PCR products were purified using QIAquick PCR Purification Kit (Qiagen), digested with EcoR1 and Bg1II (Boerhinger-Mannheim), separated by gel electrophoresis and purified using a QIAquick gel extraction kit (Qiagen).

[0557] The expression cassette, plasmid backbone and Fc4-GluGlu tag portion of the chimera were contained within a previously made in house plasmid vector. The plasmid vector was digested with EcoR1 and BamH1 (Boerhinger-Mannheim), separated by gel electrophoresis and purified using a QIAquick gel extraction kit (Qiagen). The digested and purified fragments of human OSMRbeta and Fc4-cEE containing plasmid were ligated together using T4 DNA Ligase (Life Technologies, Bethesda, Md.) using standard ligation methods. Minipreps of the resulting ligation were screened for an EcoR1/Sma1 insert of the correct size (772 bp) for the soluble OSMRbeta and positive minipreps were sequenced to confirm accuracy of the PCR reaction. This new plasmid construction is termed pZP9-ONCOMR-Fc4CEE.

[0558] B. Construction of human soluble Zcytor7/Fc4-CHIS

[0559] For construction of the hzcytor17/Fc4-CHIS portion of the heterodimer, the extracellular portion of human zcytor17 was isolated by digestion of a plasmid previously containing Zcytor17-Fc4 soluble receptor. The plasmid was first digested with Sal1 (New England Biolabs, Beverly, Mass.) after which the reaction was serially phenol chloroform extracted and ethanol precipitated. The digested DNA was then treated with T4 DNA Polymerase (Boerhinger-Mannheim), to fill in the 5′ overhangs created by the Sal1 digestion, leaving the DNA ends blunt, after which the reaction was serially phenol chloroform extracted and ethanol precipitated. The blunted DNA was then further digested with Bg1II to cut at the 3′ end.), separated by gel electrophoresis and purified using a QIAquick gel extraction kit (Qiagen) as per manufacturer's instruction. The resulting DNA fragment containing the sequence coding for the extracellular domain of zcytoR17 was ligated into an Fc4-CHIS tag containing mammalian expression vector prepared as follows.

[0560] The expression cassette, plasmid backbone and Fc4-CHIS tag portion of the chimera were contained within a previously made in house plasmid vector. This plasmid vector was digested with EcoR1 (Boerhinger-Mannheim) after which the reaction was serially phenol chloroform extracted and ethanol precipitated. The digested DNA was then treated with T4 DNA Polymerase (Boerhinger-Mannheim), to fill in the 5′ overhangs created by the EcoR1 digestion, leaving the DNA ends blunt, after which the reaction was serially phenol chloroform extracted and ethanol precipitated. The blunted DNA was then further digested with BamH1 (Boerhinger-Mannheim) to cut at the 3′ end, separated by gel electrophoresis and purified using a QIAquick gel extraction kit (Qiagen). The digested and purified fragments of human zcytor17 and Fc4-CHIS containing plasmid were ligated together using T4 DNA Ligase (Life Technologies, Bethesda, Md.) using standard ligation methods.

[0561] Minipreps of the resulting ligation were screened by PCR using the zcytor17 specific sense primer ZC29180 (SEQ ID NO: 22) and the Fc4 specific antisense primer ZC29232 (SEQ ID NO: 75) with the following PCR reaction conditions: 30 cycles of 94° C. for 60 sec., 68° C. for 150 sec; and 72° C. for 7 min. expected product size of 848 bp confirmed the correct assembly of the plasmid termed pZEM228 hzcytor17/Fc4HIS.

[0562] A second zcytor17-Fc4 construction was created for use in generating homodimer protein from COS cells. Briefly the coding region for the full fusion protein was isolated by digestion of a plasmid previously containing Zcytor17-Fc4 soluble receptor with Sal1 (Boerhinger-Mannheim). The reaction was serially phenol chloroform extracted and ethanol precipitated. The digested DNA was then treated with T4 DNA Polymerase (Boerhinger-Mannheim), to fill in the 5′ overhangs created by the EcoR1 digestion, leaving the DNA ends blunt, after which the reaction was serially phenol chloroform extracted and ethanol precipitated. The blunted DNA was then further digested with Not1 (Boerhinger-Mannheim) to cut at the 3′ end, separated by gel electrophoresis and purified using a QIAquick gel extraction kit (Qiagen). A mammalian expression vector containing a CMV driven expression cassette was digested to generate compatible ends and the 2 fragments were ligated together. Minipreps of the resulting ligation were screened by PCR using the vector specific sense primer ZC14063 (SEQ ID NO: 48) and the zcytor17 specific antisense primer ZC27899 (SEQ ID NO: 19) with the following PCR reaction conditions: 30 cycles of 94° C. for 30 sec., 64° C. for 30 sec; 70° C. for 90 sec; and 72° C. for 7 product size of approximately 1000 bp confirmed the correct assembly of the plasmid termed pZP7NX-hzcytor17-Fc4. This plasmid was subsequently transfected into COS cells using Lipofectamine (Gibco/BRL), as per manufacturer's instructions. The cells were conditioned for 60 hours in DMEM+5% FBS (Gibco/BRL) after which the protein was purified over a protein G-sepharose 4B chromatography column and made available for in vitro bioassays, for example, such as those described herein.

[0563] C. Generating a Human Zcytor17/OncostatinM Receptor (OSMRbeta)

[0564] About 16 μg each of the pZP9-ONCOMR-Fc4CEE and pZEM228 hzcytor17/Fc4HIS were co-transfected into BHK-570 (ATCC No. CRL-10314) cells using lipofectamine (Gibco/BRL), as per manufacturer's instructions. The transfected cells were selected for 10 days in DMEM+5% FBS (Gibco/BRL) containing 0.5 mg/ml G418 (Gibco/BRL) and 250 nM methyltrexate (MTX)(Sigma, St. Louis, Mo.) for 10 days.

[0565] The resulting pool of doubly-selected cells was used to generate the heterodimeric protein. Three cell Factories (Nunc, Denmark) of this pool were used to generate 10 L of serum free conditioned medium. This conditioned media was passed over a 1 ml protein-A column and eluted in (10) 750 microliter fractions. Four of these fractions found to have the highest concentration were pooled and dialyzed (10 kD MW cutoff) against PBS. The desired heterodimeric soluble zcytor17/OSMRbeta protein complex was isolated from other-media components by passing the pool over a Nickel column and washing the column with various concentrations of Imidazole. The soluble zcytor17/OSMRbeta protein eluted at intermediate concentrations of Imidazole, while hzcytor17/Fc4HIS homodimer eluted at higher concentrations of Imidazole.

[0566] Tissue Distribution of Human zcytor17 in Tissue Panels Using Northern Blot and PCR

[0567] A. Human zcytor17 Tissue Distribution using Northern Blot

[0568] Human Multiple Tissue Northern Blots (Human 12-lane MTN Blot I and II, and Human Immune System MTN Blot II; Human Endocrine MTN, Human Fetal MTN Blot II, Human Multiple Tissue Array) (Clontech) as well as in house blots containing various tissues were probed to determine the tissue distribution of human zcytor17 expression. The in-house prepared blots included the following tissue and cell line mRNA: SK-Hep-1 cells, THP1 cells, Adrenal gland (Clontech); Kidney (Clontech), Liver (Clontech and Invitrogen); Spinal cord (Clontech), Testis (Clontech), Human CD4+ T-cells, Human CD8+ T-cells, Human CD19+ T-cells, human mixed lymphocyte reaction (MLR), THP1 cell line (ATCC No. TIB-202), U937 cell line, p388D1 mouse lymphoblast cell line (ATCC No. CCL-46) with or without stimulation by Ionomycin; and WI-38 human embryonic lung cell line (ATCC No. CRL-2221) with or without stimulation by Ionomycin.

[0569] An approximately 500 bp PCR derived probe for zcytor17 (SE ID NO: 4) was amplified using oligonucleotides ZC28,575 (SEQ ID NO: 77) and ZC27,899 (SEQ ID NO: 19) as primers. The PCR amplification was carried out as follows: 30 cycles of 94° C. for 1 minute, 65° C. for 1 minute, and 72° C. for 1 minute; followed by 1 cycle at 72° C. for 7 minutes. The PCR product was visualized by agarose gel electrophoresis and the approximately 500 bp PCR product was gel purified as described herein. The probe was radioactively labeled using the PRIME IT II™ Random Primer Labeling Kit (Stratagene) according to the manufacturer's instructions. The probe was purified using a NUCTRAP™ push column (Stratagene). EXPRESSHYB™ (Clontech) solution was used for the prehybridization and as a hybridizing solution for the Northern blots. Prehybridization was carried out at 68° C. for 2 hours. Hybridization took place overnight at 68° C. with about 1.5×10⁶ cpm/ml of labeled probe. The blots were washed three times at room temperature in 2×SSC, 0.05% SDS, followed by 1 wash for 10 minutes in 2×SSC, 0.1% SDS at 50° C. Several faint bands were seen after several days exposure. An approximately 9 kb transcript was seen in trachea, skeletal muscle and thymus; an approximately 2 kb transcript was seen in PBL, HPV, U937 and THP-1 cells; and about a 1.2 kb transcript was seen in placenta, bone marrow and thyroid, and HPV and U937 cells. In all the tissues listed above, the signal intensity was faint. There appeared to be little expression in most normal tissues, suggesting that zcytor17 expression may be dependent on activation of the cell or tissues in which it is expressed.

[0570] B. Tissue Distribution in Tissue Panels Using PCR

[0571] A panel of cDNAs from human tissues was screened for zcytor17 expression using PCR. The panel was made in-house and contained 94 marathon cDNA and cDNA samples from various normal and cancerous human tissues and cell lines as shown below in Table 13. The cDNAs came from in-house libraries or marathon cDNAs from in-house RNA preps, Clontech RNA, or Invitrogen RNA. The marathon cDNAs were made using the marathon-Ready™ kit (Clontech, Palo Alto, Calif.) and QC tested with clathrin primers ZC21195 (SEQ ID NO: 78) and ZC21196 (SEQ ID NO: 79) and then diluted based on the intensity of the clathrin band. To assure quality of the panel samples, three tests for quality control (QC) were run: (1) To assess the RNA quality used for the libraries, the in-house cDNAs were tested for average insert size by PCR with vector oligos that were specific for the vector sequences for an individual cDNA library; (2) Standardization of the concentration of the cDNA in panel samples was achieved using standard PCR methods to amplify full length alpha tubulin or G3PDH cDNA using a 5′ vector oligo ZC14,063 (SEQ ID NO: 48) and 3′ alpha tubulin specific oligo primer ZC17,574 (SEQ ID NO: 49) or 3′ G3PDH specific oligo primer ZC17,600 (SEQ ID NO: 50); and (3) a sample was sent to sequencing to check for possible ribosomal or mitochondrial DNA contamination. The panel was set up in a 96-well format that included a human genomic DNA (Clontech, Palo Alto, Calif.) positive control sample. Each well contained approximately 0.2-100 pg/μl of cDNA. The PCR reactions were set up using oligos ZC26,358 (SEQ ID NO: 80) and ZC26,359 (SEQ ID NO: 81), TaKaRa Ex Taq™ (TAKARA Shuzo Co LTD, Biomedicals Group, Japan), and Rediload dye (Research Genetics, Inc., Huntsville, Ala.). The amplification was carried out as follows: 1 cycle at 94° C. for 2 minutes, 35 cycles of 94° C. for 30 seconds, 66.3° C. for 30 seconds and 72° C. for 30 seconds, followed by 1 cycle at 72° C. for 5 minutes. About 10 μl of the PCR reaction product was subjected to standard agarose gel electrophoresis using a 4% agarose gel. The correct predicted DNA fragment size was observed in lymph node, prostate, thyroid, HPV (prostate epithelia), HPVS (prostate epithelia, selected), lung tumor, uterus tumor reactions, along with the genomic DNA reaction.

[0572] The DNA fragment for prostate tissue (2 samples), HPV (prostate epithelia), HPVS (prostate epithelia, selected), and genomic were excised and purified using a Gel Extraction Kit (Qiagen, Chatsworth, Calif.) according to manufacturer's instructions. Fragments were confirmed by sequencing to show that they were indeed zcytor17.

[0573] C. Expression Analysis of zcytoR17 by PCR and Northern

[0574] Annotation of the cell types and growth conditions that affect expression of the receptor is a useful means of elucidating its function and predicting a source of ligand. To that end a wide variety of tissue and cell types were surveyed by PCR. The thermostable polymerase Advantage II™ (Clontech, La Jolla, Calif.) was used with the oligonucleotide primers ZC29,180 (SEQ ID NO: 22) and ZC29,179 (SEQ ID NO: 82) and 1-10 ng of the various cDNA templates listed below for 30 amplification cycles of (94° C., 30 sec.; 66° C., 20 sec.; 68° C., 1 min. 30 sec.). Following this, 20% reaction was run out on 0.8% agarose, TAE/ethidium bromide gels and visualized with UV light. Samples were then scored on the basis of band intensity. See Table 14 below.

[0575] Of the strong positive PCR signals, two were from the human monocyte cell lines U937 and THP1.

[0576] These two cell lines along with a prostate epithelia line were selected for further analysis by Northern blot. Previous attempts at visualizing a transcript by northern analysis using mRNA from various tissues yielded weak and diffuse signals in the surprisingly large size range of 7-10 kb making this data difficult to interpret. A denaturing formaldehyde/MOPS/0.8% agarose gel was prepared (RNA Methodologies, Farrell, RE Academic Press) and 2 μg of polyA+ mRNA was run for each sample along side an RNA ladder (Life Technologies, Bethesda, Md.). The gel was then transferred to Hybond nylon (Amersham, Buckinghamshire, UK), UV crosslinked, and hybridized in ExpressHyb solution (Clontech, LaJolla, Calif.) at 68° C. overnight using a probe to human zcytoR17 generated by PCR with the oligos ZC28,575 (SEQ ID NO: 77), and ZC27,899 (SEQ ID NO: 19) and labeled with a Megaprime ³²p kit (Amersham). The northern blot was subsequently washed with 0.2×SSC+0.1% SDS at 65° C. for 15 minutes and exposed to film for 7 days with intensifying screens. A prominent 8kb band was seen in both the prostate epithelia and U937 lanes while a fainter band was present in the THP1 lane.

[0577] To optimize the cDNA used as a hybridization probe, four different regions of the full-length human zcytoR17 sequence were amplified by PCR, labeled and hybridized as described above to southern blots containing genomic and amplified cDNA library DNA. The four probes, herein designated probes A-D, were amplified using the following primer pairs: (A) ZC28,575 (SEQ ID NO: 77), ZC27,899 (SEQ ID NO: 19); (B) ZC27,895 (SEQ ID NO: 20), ZC28,917 (SEQ ID NO: 83); (C) ZC28,916 (SEQ ID NO: 84), ZC28,918 (SEQ ID NO: 85); and (D) ZC28,916 (SEQ ID NO: 84), ZC29,122 (SEQ ID NO: 21). Human genomic DNA along with amplified cDNA libraries demonstrated to contain zcytor17 by PCR were digested with EcoR1 and Xho1 to liberate inserts and run out on duplicate TAE/0.8% agarose gels, denatured with 0.5M NaOH, 1.5 M NaCl, blotted to Hybond, UV crosslinked and each hybridized with a distinct probe. Probe B was found to have the least nonspecific binding and strongest signal. Thus, Probe B was used for all subsequent hybridizations.

[0578] Given that the THP1 cells are an excellent model of circulating monocytes and expressed zcytor17 at low levels we treated them with a variety of compounds in an effort to increase expression of zcytoR17. The cells were grown to a density of 2e5/ml, washed and resuspended in various stimulating media, grown for four or thirty hours, and harvested for RNA preparations. Each media was supplemented with one of the following drugs or pairs of cytokines: LPS 2 ug/ml (Sigma Chemicals, St. Louis, Mo.), hTNFα2 ng/ml (R&D Systems, Minneapolis, Minn.), hGM-CSF 2 ng/ml (R&D Systems, Minneapolis, Minn.), hIFNγ 50 ng/ml (R&D Systems, Minneapolis, Minn.), hMCSF 1 ng/ml (R&D Systems, Minneapolis, Minn.), hIL6 1 ng/ml (R&D Systems, Minneapolis, Minn.), hIL1β 2 ng/ml (R&D Systems, Minneapolis, Minn.), hIFNγ 50 ng/ml+hIL4 0.5 ng/ml (R&D Systems, Minneapolis, Minn.), hIFNγ 50 ng/ml+hIL10 1 ng/ml (R&D Systems, Minneapolis, Minn.), PMA 10 ng/ml (Calbiochem, San Diego, Calif.) and an untreated control. At the end of the culture period Total RNA was prepared using an RNAeasy Midi-kit (Qiagen, Valencia, Calif.). Poly A+ RNA was selected from the total RNA using an MPG kit (CPG, Lincoln Park, N.J.). Two micrograms of polyA+ RNA from each condition was run on formaldehyde/MOPS/agarose gels, transferred to nylon and UV crosslinked as described above. These northern blots were then hybridized, as above, to probe B at 68° C. overnight, washed at high stringency with 0.2×SSC, 0.1% SDS at 65C., exposed to film overnight then exposed to phosphor screens for signal quantitation. A dominant 8 kb mRNA as well a relatively weaker 2.8 kb band were seen in all lanes. A 20-fold increase in zcytor17 mRNA was seen in RNA from cells treated with hIFNγ for 30 hours, this effect was slightly muted with simultaneous treatment with IL4. Minor 3 fold increases in mRNA were seen in RNA from cells treated with LPS, TNFα and GM-CSF while MCSF, IL6, and IL1β had no effect on zcytor17 mRNA levels. Taken together this data suggests a role for the zcytor17 receptor and its ligand in monocyte macrophage biology and by extension any number of disease processes in which these cells participate.

[0579] Tissue Distribution of Human zcytor17 in Tissue Panels Using Northern Blot and PCR

[0580] A human zcytor17lig cDNA fragment was obtained using PCR with gene specific primers: Sense primer ZC41438 (SEQ ID NO: 93) and antisense primer ZC41437 (SEQ ID NO: 94) and template human zcytor17lig cDNA (SEQ ID NO: 90) This fragment was purified using standard methods and about 25 ng labeled with ³²p alpha dCTP using the Prime-It RmT random primer labeling kit (Stratagene) and hybridized in Ultrahyb, (Ambion) and used to expose Biomax film/intensifying screens per the manufacturer's recommendations in each case. New, previously unused blots Including the Clontech Human 12 lane MTN, the human brain MTN II, and the human brain MTN blot IV, the human immune system MTN II, and the human MTE array II, lo from Clontech were hybridized overnight at 42° C. per the Ambion ultrahyb method. Non-specific radioactive counts were washed off using 0.1SSC/0.5% SDS at 55° C. The positive blots included the human 12 lane MTN (Clontech). Of the 12 tissues examined, only placenta was positive for an approximately 1.2 KB transcript.

[0581] Construction of Mammalian Expression Vectors that Express Human zcytor17lig-CEE

[0582] A. Construction of zCytor17Lig-CEE/pZMP21

[0583] An expression plasmid containing all or part of a polynucleotide encoding zCytor17Lig-CEE (SEQ ID NO: 95) was constructed via homologous recombination. The plasmid was called zCytor17Lig-CEE/pZMP21.

[0584] The construction of zCytor1 7Lig-CEE/pZMP21 was accomplished by. generating a zCytor17Lig-CEE fragment using PCR amplification. The DNA template used for the production of the zCytor17Lig-CEE fragment was zCytor17Lig/pZP7nx. The primers used for the production of the zCytor17Lig-CEE fragment were: (1) ZC41,607 (SEQ ID NO: 97) (sense sequence), which includes from the 5′ to the 3′ end: 28bp of the vector flanking sequence (5′ of the insert) and 21 bp corresponding to the 5′ sequence of zCytor17Lig; and (2) ZC41,605 (SEQ ID NO: 98) (anti-sense sequence), which includes from the 5′ to the 3′ end: 37 bp of the vector flanking sequence (3′ of the insert), 3 hp of the stop codon, 21 bp encoding a C-terminal EE tag, and 21 bp corresponding to the 3′ end of zCytor17Lig sequence. The fragment resulting from the above PCR amplification is a copy of the template zCytor17Lig with the addition of a C-terminal EE tag, yielding a final product zCytor17Lig-CEE.

[0585] PCR reactions were run as follows: To a 100 μl final volume was added: 10 μl of 10×Taq Polymerase Reaction Buffer with 15 mM MgCl (Gibco), 1μl of Taq DNA Polymerase (5 units/μl, Gibco), 3μl of 10 mM dNTPs, 78μl dH₂O, 3 μl of a 20 pmol/μl stock of primer ZC41,607 (SEQ ID NO: 97) 3 μl of a 20 pmol/μl stock of primer ZC41,605 (SEQ ID NO: 98), and 2 μl of a 0.13 μg/μl stock of zCytor17lig template DNA. A volume equal to 50 μl of mineral oil was added to the mixture. The reaction was heated to 94° C. for 5 minutes, followed by 35 cycles at 94° C. for 1 minute; 55° C. for 2 minutes; 72° C. for 3 minutes; followed by a 10 minute extension at 72° C. and held at 4° C. until the reaction was collected.

[0586] The plasmid pZMP21 was restriction digested with Bg1II enzyme, cleaned with a QiaQuick PCR Purification Kit (Qiagen) using a microcentrifuge protocol, and used for recombination with the PCR fragment. Plasmid pZMP21 was constructed from pZMP20 which was constructed from pZP9 (deposited at the American Type Culture Collection, 10801 University Boulevard, Manassas, Va. 20110-2209, and is designated No. 98668) with the yeast genetic elements from pRS316 (deposited at the American Type Culture Collection, 10801 University Boulevard, Manassas, Va. 20110-2209, and designated No. 77145), an IRES element from poliovirus, and the extracellular domain of CD8, truncated at the carboxyl terminal end of the transmembrane domain. PZMP21 is a mammalian expression vector containing an expression cassette having the MPSV promoter, immunoglobulin signal peptide intron, multiple restriction sites for insertion of coding sequences, a stop codon and a human growth hormone terminator. The plasmid also has an E. coli origin of replication, a mammalian selectable marker expression unit having an SV40 promoter, enhancer and origin of replication, a DHFR gene, the SV40 terminator, as well as the URA3 and CEN-ARS sequences required for selection and replication in S. cerevisiae.

[0587] Fifty microliters of competent yeast cells (S. cerevisiae) were independently combined with 100 ng of cut plasmid, 5 μl of previously described PCR mixture, and transferred to a 0.2 cm electroporation cuvette. The yeast/DNA mixture was electropulsed at 0.75 kV (5 kV/cm), ∞ ohms, 25 μF. Each cuvette had 600 μl of 1.2 M sorbitol added, and the yeast was plated in one 100 μl aliquot and one 300 μl aliquot onto two URA-D plates and incubated at 30° C. After about 72 hours, the Ura+ yeast transformants from a single plate were resuspended in 1 ml H₂O and spun briefly to pellet the yeast cells. The cell pellet was resuspended in 500 μl of lysis buffer (2% Triton X-100, 1% SDS, 100 mM NaCl, 10 mM Tris, pH 8.0, 1 mM EDTA). The 500 μl of the lysis mixture was added to an Eppendorf tube containing 300 μl acid washed 600 μm glass beads and 300 μl phenol-chloroform, vortexed for 1 minute intervals two or three times, followed by a 5 minute spin in a Eppendorf centrifuge at maximum speed. Three hundred microliters of the aqueous phase was transferred to a fresh tube, and the DNA precipitated with 600 μl 100% ethanol (EtOH), followed by centrifugation for 10 minutes at 4° C. The DNA pellet was then washed with 500μl 70% EtOH, followed by centrifugation for 1 minute at 4° C. The DNA pellet was resuspended in 30 μl H₂O.

[0588] Transformation of electrocompetent E. coli cells (MC1061) was done with 5 μl of the yeast DNA prep and 50 μl of MC1061 cells. The cells were electropulsed at 2.0 kV, 25 μF and 400 ohms(Ω). Following electroporation, 600 μl SOC (2% Bacto' Tryptone (Difco, Detroit, Mich.), 0.5% yeast extract (Difco), 10 mM NaCl, 2.5 mM KCl, 10 mM MgCl₂, 10 mM MgSO₄, 20 mM glucose) was added. The electroporated E. coli cells were plated in a 200 μl and a 50 μl aliquot on two LB AMP plates (LB broth (Lennox), 1.8% Bacto Agar (Difco), 100 mg/L Ampicillin). The plates were incubated upside down for about 24 hours at 37° C. Three Ampicillin-resistant colonies were selected at random and submitted for sequence analysis of the insert. Large-scale plasmid DNA was isolated from a sequence-confirmed clone using the Qiagen Maxi kit (Qiagen) according to manufacturer's instructions.

[0589] B. Construction of Mouse zCytor17Lig(m)-CEEIpZMP21

[0590] An expression plasmid containing the entire polynucleotide encoding murine zCytor17Lig-CEE (SEQ ID NO: 104 and SEQ ID NO: 105) was also constructed via homologous recombination using the method described in Example 33A above. The primers used were: (1) ZC41643 (SEQ ID NO: 106) (forward, 5′ to 3′ sense) having a 28 bp vector overlap 5′ of the insertion point; 21 bp of the 5′ end of zcytor17lig(m) and (2) ZC41641 (SEQ ID NO: 107) (reverse, 5′ to 3′ anti-sense) having a 37bp vector overlap 3′ of the insertion point; 3 bp stop codon; 21 bp C-terminal EE tag; 24 bp of the 3′ end of zCytor17Lig(m)-CEE. The plasmid was called zcytor17lig(m)-CEE/pZMP21. The polynucleotide sequence of zcytor17lig(m)-CEE is shown in SEQ ID NO: 104, and corresponding polypeptide sequence is shown in SEQ ID NO: 105.

[0591] Transfection and Expression of zcytor17lig-CEE Polypeptides

[0592] A. Expression of Human zCytor17Lig-CEE/pZMP21 in 293T Cells

[0593] ZCytor17Lig-CEE was expressed transiently in 293T cells (Stanford University School of Medicine, Stanford, Calif.; ATCC No. SD-3515) to generate initial purified protein. The day before the transfection, 293T cells were seeded at 6.5×10⁴ cells/cm² in 30 T162 culture flasks with a total volume of 30 ml of culture media (SL7V4+5% FBS+1% Pen/Strep) per flask. The cells were allowed to incubate for 24 hours at 37° C.

[0594] A DNA/Liposome mixture was prepared as follows: Two 50 ml conical tubes were filled with 25 mLs of transfection media (SL7V4+1% Pen/Strep) and 1.13 mg of zCytor17Lig-CEE/pZMP21 (Example 33) was added to each. A separate set of two 50 ml conical tubes were filled with 22 ml of transfection media (above) and 3 ml of liposomes (Lipofectamine, Gibco) was added to each. For each set of tubes, one tube of DNA was added to one tube of liposomes and the DNA/liposome mix was incubated for 30 minutes. The two 50 ml conical tubes containing the DNA/liposome mixtures were pooled (about 100 ml) and 300 ml of transfection media was added. The 30 flasks of the 293T cells were decanted, washed 1× with about 15 ml of PBS, and 12.5 ml of the diluted DNA/liposome mixture was added to each flask. The flasks were incubated for 3 hours at 37° C. After the incubation period, 25 ml of culture media (above) were added to each T162 flask. The transfection media was harvested after approximately 96 hours and was used for protein purification (Example 35).

[0595] B. Expression of Mouse zCytor17Lig-CEE(m)/pZMP21 in 293T Cells

[0596] Mouse zCytor17Lig(m)-CEE was expressed transiently in 293T cells as described in Example 34A and cultured media was used for protein purification (Example 35).

Example 35

[0597] Purification of Zcytor17lig- CEE from 293T Cells

[0598] Unless otherwise noted, all operations were carried out at 4° C. The following procedure was used for purifying both mouse and human Zcytor17lig containing C-terminal Glu-Glu (EE) tags (SEQ ID NO: 103). Conditioned media from 293T cells expressing Zcytor17lig-CEE (Example 34) was purified. Total target protein concentrations of the conditioned media were determined via SDS-PAGE and Western blot analysis with the anti-EE antibody.

[0599] A 5.5 ml column of anti-EE Poros 50 A (PE BioSystems, Framingham, Mass.) (prepared as described below) was poured in a Waters AP-1, 1 cm×7 cm glass column (Waters, Milford, Mass.). The column was flow packed and equilibrated on a BioCad Sprint (PE BioSystems, Framingham, Mass.) with phosphate buffered saline (PBS) pH 7.4. The conditioned media was adjusted with NaCl to 0.3 M and the pH adjusted to 7.2. The conditioned media was then loaded on the column overnight with about 3 ml/minute flow rate. The column was washed with 10 column volumes (CVs) of PBS pH 7.4, and again washed with 3CVs 5×Sigma PBS pH 7.4. It was step eluted with 0.5 M Acetate, 0.5 M NaCl, pH 2.5 at 3 ml/minute. The fraction tubes contained 1 ml Tris base (no pH adjustment) to neutralize the elution immediately. The column was again washed for 2CVs with 5×Sigma PBS, pH 7.4 to neutralize the column and then equilibrated in PBS (pH 7.4). Two ml fractions were collected over the entire elution chromatography and absorbance at 280 and 215 nM were monitored; the pass through and wash pools were also saved and analyzed. The 5×PBS and the acid elution peak fractions were analyzed for the target protein via SDS-PAGE Silver staining and Western Blotting with the primary antibody anti-EE and secondary antibody, anti mouse-HRP conjugated. The acid elution fractions of interest were pooled and concentrated from 38 ml to 0.8 ml using a 5000 Dalton molecular weight cutoff membrane spin concentrator (Millipore, Bedford, Mass.) according to the manufacturer's instructions.

[0600] To separate Zcytor17lig-CEE from aggregated material and any other contaminating co-purifying proteins, the pooled concentrated fractions were subjected to size exclusion chromatography on a 1.6×60 cm (120 ml) Superdex 75 (Pharmacia, Piscataway, N.J.) column equilibrated and loaded in PBS at a flow rate of 1.0 ml/min using a BioCad Sprint. Three milliliter fractions were collected across the entire chromatography and the absorbance at 280 and 215 nM were monitored. The peak fractions were characterized via SDS-PAGE Silver staining, and only the most pure fractions were pooled. This material represented purified Zcytor17lig -CEE protein.

[0601] On Western blotted, Coomassie Blue and Silver stained SDS-PAGE gels, the Zcytor17lig-CEE was one major band. The protein concentration of the purified material was performed by BCA analysis (Pierce, Rockford, Ill.) and the protein was aliquoted, and stored at −80° C. according to standard procedures.

[0602] To prepare PorosA50 anti-EE, a 65 ml bed volume of Poros A50 (PE Biosystems) was washed with 100 ml of water and then 0.1 M triethanolamine, pH 8.2 (TEA, ICN, Aurora, Ohio), 1 M Na₂SO₄, pH 8.8 containing 0.02% sodium azide using a vacuum flask filter unit. The EE monoclonal antibody solution, at a concentration of 2 mg/ml in a volume of 300 ml, was mixed with the washed resin in a volume of 250 ml. After an overnight incubation at room temperature, the unbound antibody was removed by washing the resin with 5 volumes of 200 mM TEA, 1 M Na₂SO₄, pH 8.8 containing 0.02% sodium azide as described above. The resin was resuspended in 2 volumes of TEA, 1 M Na₂SO₄, pH 8.8 containing 0.02% sodium azide and transferred to a suitable container. Three ml of 25 mg/ml (68 mM) Disuccinimidyl suberate (in DMSO supplied by Pierce, Rockford, Ill.) is added and the solution is incubated for three hours at room temperature. Nonspecific sites on the resin were then blocked by incubating for 10 min at room temperature with 5 volumes of 20 mM ethanolamine (Sigma, St. Louis, Mo.) in 200 mM TEA, pH 8.8 using the vacuum flask filter unit. The resin is washed with PBS, pH 7.4, followed by 0.1 M Glycine, pH 3 and then neutralized with 10×PBS. After washing with distilled water, the final coupled anti-EE Poros-A 50 resin was stored at 4° C. in 20% Ethanol.

[0603] N-terminal Sequencing of Human and Mouse Zcytor17lig

[0604] A. N-terminal Sequencing of Human Zcytor17lig

[0605] Standard automated N-terminal polypeptide sequencing (Edman degradation) was performed using reagents from Applied Biosystems. N-terminal sequence analysis was performed on a Model 494 Protein Sequencer System (Applied Biosystems, Inc., Foster City, Calif.). Data analysis was performed with Model 610A Data Analysis System for Protein Sequencing, version 2.1a (Applied Biosystems).

[0606] A purified human zcytor17lig-CEE sample (Example 35) was supplied. The sample was loaded onto a prepared glass fiber filter for n-terminal sequencing. The glass fiber filter was prepared by precycling it with Biobrene™.

[0607] N-terminal sequence analysis of the secreted human zcytor17lig polypeptide did not verify the predicted cleavage site of the signal sequence but resulted in a mature start at residue 27(Leu) in SEQ ID NO: 2 of the human zcytor17lig precursor sequence.

[0608] B. N-terminal Sequencing of Human Zcytor17lig

[0609] Standard automated N-terminal polypeptide sequencing (Edman degradation) was performed using reagents from Applied Biosystems. N-terminal sequence analysis was performed on a Model 494 Protein Sequencer System (Applied Biosystems, Inc., Foster City, Calif.). Data analysis was performed with Model 610A Data Analysis System for Protein Sequencing, version 2.1a (Applied Biosystems).

[0610] A purified mouse zcytor17lig-CEE sample was supplied as captured on Protein G Sepharose/anti-EE beads (Example 35). The beads were placed in reducing SDS PAGE sample buffer and on a boiling water bath before running on SDS PAGE, using a Novex SDS PAGE system (4-12% Bis-Tris MES NuPAGE; Invitrogen) as per manufacturer's instructions. The gel was electrotransferred to a Novex PVDF membrane (Invitrogen), and Coomassie blue stained (Sigma, St. Louis, Mo.) using standard methods. Corresponding anti-EE Western blots were performed to identify the zcytor17lig band for N-terminal protein sequencing. The mouse anti-EE IgG HRP conjugated antibody used was produced in house.

[0611] N-terminal sequence analysis of the secreted mouse zcytor17lig polypeptide verified the predicted cleavage site of the signal sequence resulting in a mature start at 31 (Ala) in reference to SEQ ID NO: 11 and SEQ ID NO: 91 of the mouse zcytor17lig precursor sequence.

Example 37

[0612] Cos Cell Binding Assay

[0613] A binding assay was used to test the binding of the zcytor17lig to receptors comprising zcytor17 receptor, such as the zcytor17 receptor or receptor heterodimers and trimers comprising zcytor17 receptor (e.g., zcytor17/OSMR, zcytor17/WSX-1, or zcytor17/OSMR/WSX-1, or other Class I cytokine receptor subunits). Zcytor17 receptor plasmid DNA was transfected into COS cells and transfected COS cells were used to assess binding of the zcytor17lig to receptors comprising zcytor17 receptor as described below.

[0614] A. COS Cell Transfections

[0615] The COS cell transfection was performed as follows: Mix 800 ng receptor plasmid DNA in the following combinations: pZp7pX/zcytor17 alone; pZp7Z/WSX-1 alone; pZp7NX/OSMR alone; pZp7pX/zcytor17+pZp7NX/OSMR; pZp7pX/zcytor17+pZp7Z/WSX-1; pZp7NX/OSMR+pZp7Z/WSX-1; pZp7pX/zcytor17+pZp7NX/OSMR+pZp7Z/WSX-1) and 4 ul Lipofectamine™ in 80 μl serum free DMEM media (55 mg sodium pyruvate, 146 mg L-glutamine, 5 mg transferrin, 2.5 mg insulin, 1 μg selenium and 5 mg fetuin in 500 ml DMEM), incubate at room temperature for 30 minutes and then add 320 μl serum free DMEM media. Add this 400 ul mixture onto 2×10⁵ COS cells/well plated on 12-well tissue culture plate (fibronectin-coated) and incubate for 5 hours at 37° C. Add 500 ul 20% FBS DMEM media (100 ml FBS, 55 mg sodium pyruvate and 146 mg L-glutamine in 500 ml DMEM) and incubate overnight.

[0616] B. Binding Assay

[0617] The binding assay was performed as follows: media was rinsed off cells with PBS+0.1% BSA, and then cells were blocked for 60 minutes with the same solution. The cells were then incubated for 1 hour in PBS+0.1 % BSA with 1.0 μg/ml zcytor17ligCEE purified protein. Cells were then washed with PBS+0.1% BSA and incubated for another hour with 1:1000 diluted mouse anti-GluGlu antibody. Again cells were washed with PBS+0.1% BSA, then incubated for 1 hour with 1:200 diluted goat anti-mouse-HRP conjugated antibody.

[0618] Positive binding was detected with fluorescein tyramide reagent diluted 1:50 in dilution buffer (NEN kit) and incubated for 4-6 minutes, and washed with PBS+0.1% BSA. Cells were fixed for 15 minutes with 1.8% Formaldehyde in PBS, then washed with PBS+0.1% BSA. Cells were preserved with Vectashield Mounting Media (Vector Labs Burlingame, Calif.) diluted 1:5 in PBS. Cells were visualized using a FITC filter on fluorescent microscope.

[0619] Positive binding was detected for cells transfected with zcytor17 only, zcytor17+OSMRbeta, zcytor17+WSX-1, and zcytor17+OSMRbeta+WSX-1. No binding was detected for cells transfected with WSX-1+OSMRbeta, with OSMRbeta only, or with WSX-1 only.

[0620] Mouse zcytor17lig Activates Mouse zcytor17/OSMRbeta Receptor-In Luciferase Assay

[0621] A. Cloning of Full-Length Mouse zcytor17 and Mouse OSMRbeta for Expression

[0622] A mouse testes cDNA library was screened for a full-length clone of mouse zcytoR17. The library was plated at 65,500 cfu/plate on 24 LB+Amp plates. Filter lifts were prepared using Hybond N (Amersham-Pharmacia Biotech, Inc., Piscataway, N.J.) on a total of approximately 1.6 million colonies. The filters were marked with a hot needle for orientation and then denatured for 6 minutes in 0.5 M NaOH and 1.5 M Tris-HCl, pH 7.2. The filters were then neutralized in 1.5 M NaCl and 0.5 M Tris-HCl, pH 7.2 for 6 minutes. The DNA was affixed to the filters using a UV crosslinker (Stratalinker®, Stratagene, La Jolla, Calif.) at 1200 joules. The filters were then left to dry overnight at room temperature.

[0623] The next day, the filters were pre-washed at 65° C. in pre-wash buffer consisting of 0.25×SSC, 0.25% SDS and 1 mM EDTA. Cell debris was manually removed using Kimwipes® (Kimberly-Clark) and the solution was changed 3 times over a period of 1 hour. Filters were air dried and stored at room temperature until needed. The filters were then prehybridized for approximately 3 hours at 63° C. in 20 ml of ExpressHyb™Hybridization Solution (Clontech, Palo Alto, Calif.).

[0624] Probe B (Example 31) was generated by PCR from human zcytoR17 template using oligonucleotide primers ZC27,895 (SEQ ID NO: 20) and ZC28,917 (SEQ ID NO: 83) and was radioactively labeled with ³²p using a commercially available kit (Megaprime DNA Labeling System; Amersham Pharmacia Biotech, Piscataway, N.J.) according to the manufacturer's instructions. The probe was purified using a Stratagene™ push column (NucTrap® column; Stratagene, La Jolla, Calif.). The probe was denatured at 100° C. for 15 min and added to ExpressHyb™. Filters were hybridized in 15 ml hybridizing solution containing 1.6×10⁶ cpm/ml of probe at 63° C. overnight. Filters were washed at 55° C. in 2×SSC, 0.1 % SDS and 1 mM EDTA and exposed to X-ray film at −80° C. for 4 ½ days. Thirteen positives were picked from the plates as plugs and placed in 1 ml LB+amp in 1.7 ml tubes. Tubes were placed at 4° C. overnight. These 13 positives were subjected to two further rounds of purification. The tertiary plates were outgrown at 37° C. after filter lifts were taken and single colonies were picked and sent to sequencing. Three of these were determined to contain sequence of the mouse ortholog of zcytoR17.

[0625] In addition, a PCR product was generated using CTLL-2 cDNA as a template and oligonucleotides ZC38,239 (SEQ ID NO: 123) and ZC38,245 (SEQ ID NO: 124) as primers. CTLL-2 is a mouse cytotoxic T lymphocyte cell line (ATCC No. TIB-214). This PCR reaction was run as follows: 1 cycle at 95° C. for 1 minute, 30 cycles at 95° C. for 15 seconds, 68° C. for 3 minutes, then 68° C. for 10 minutes; 4° C. soak. The PCR reaction used approximately 0.5 ng of cDNA, 20 pmoles of each oligonucleotide, and 1 μl of Advantage II polymerase mix (ClonTech). About 6% of the PCR product was used as a template in a new PCR reaction, as above, except with oligonucleotides ZC38,239 (SEQ ID NO: 123) and ZC38,238 (SEQ ID NO: 125). This PCR reaction was run as follows: 30 cycles at 94° C. for 45 seconds, 65° C. for 45 seconds, 72° C. for 1 minute, then 72° C. for 7 minutes; 10° C. soak. Most of the PCR reaction was loaded on a 1.0% agarose gel and the predominant band at approximately 360 bp was excised, the DNA fragment was eluted, and DNA sequencing was performed.

[0626] The sequence of the mouse zcytor17 polynucleotide is shown in SEQ ID NO: 126 and the corresponding amino acid sequence shown in SEQ ID NO: 127. In addition, a truncated soluble form of the mouse zcytor17 polynucleotide is shown in SEQ ID NO: 128 and the corresponding amino acid sequence shown in SEQ ID NO: 129.

[0627] To obtain a full-length mouse OSMRbeta cDNA, 5′ and 3′ PCR products were isolated and joined using an internal BamHI site. The PCR primers were designed using the nucleotide sequence SEQ ID NO: 134 and include EcoRI and XbaI restriction sites for cloning purposes. The genomic mouse OSMRbeta nucleic acid sequence is shown in SEQ ID NO: 134, wherein the coding sequence encompasses residues 780 to 3692 encoding a mouse OSMRbeta 970 amino acid polypeptide, which is shown in SEQ ID NO: 135. A degenerate nucleic acid sequence which encodes the polypeptide of SEQ ID NO: 135 is shown in SEQ ID NO: 136.

[0628] A 5′ PCR product was generated using an in-house 3T3-L1 (differentiated mouse adipocyte) cDNA library as a template and oligonucleotides ZC41,764 (SEQ ID NO: 130) and ZC41,598 (SEQ ID NO: 131) as primers. This 5′ PCR reaction was run as follows: 30 cycles at 95° C. for 45 seconds, 55° C. for 45 seconds, 72° C. for 1 minute 30 seconds, then 72° C. for 7 minutes; 4° C. soak. The PCR reaction used approximately 3 μg of plasmid prepared from the cDNA library, 20 pmoles of each oligonucleotide, and five units of Pwo DNA polymerase (Roche). About 90% of the 5′ PCR product was digested with EcoRI and BamHI and gel purified on a 1.0% agarose gel. The approximately 1446 bp band was excised and used for ligation (see below).

[0629] A 3′ PCR product was generated using a mouse placenta in-house cDNA library as a template and oligonucleotides ZC41,948 (SEQ ID NO: 132) and ZC41,766 (SEQ ID NO: 133) as primers. This 3′ PCR reaction was run as follows: 30 cycles at 95° C. for 45 seconds, 55° C. for 45 seconds, 72° C. for 1 minute 30 seconds, then 7 minutes; 4° C. soak. The PCR reaction used approximately 3 μg of plasmid prepared from the cDNA library, 20 pmoles of each oligonucleotide, and five units of Pwo DNA polymerase (Roche). About 90% of the 3′ PCR product was digested with BamHI and XbaI and gel purified on a 1.0% agarose gel. The approximately 2200 bp band was excised and used for ligation along with the 5′ PCR product (described above) to the expression vector pZP-5Z digested with EcoRI and XbaI. The three-part ligation was performed with the 5′ EcoRI to BamHI fragment above, the 3′ BamHI to XbaI fragment, and the expression vector pZP-5Z digested with EcoRI and XbaI. This generated a pZP-5Z plasmid containing a full-length cDNA for mouse OSMRbeta (nucleotides 780 to 3692 of SEQ ID NO: 134), designated pZP-5Z/OSMRbeta. The full length mouse OSMRbeta cDNA in pZP5Z/OSMRbeta has two amino acid insertions from SEQ ID NO: 135. There is a duplication of amino acid Glycine at position 370 and a duplication of amino acid Glutamic Acid at position 526. Plasmid pZP-5Z is a mammalian expression vector containing an expression cassette having the CMV promoter, multiple restriction sites for insertion of coding sequences, and a human growth hormone terminator. The plasmid also has an E. coli origin of replication, a mammalian selectable marker expression unit having an SV40 promoter, enhancer and origin of replication, a zeocin resistance gene and the SV40 terminator.

[0630] The resulting transformants were sequenced to confirm the mouse OSMRbeta cDNA sequence.

[0631] B. Construction of BaF3/KZ134/zcytor17m, BaF3/KZ134/zcytor17m/OSMRbetam, BHK/KZ134/zcytor17m, and BHK/KZ134/zcytor17m/OSMRbetam Cell Lines

[0632] Stable BaF3/KZ134 and BHK/KZ134 cell lines (Example 20) were transfected with an expression plasmid encoding full-length mouse zcytor17, pZP-7P/zcytor17m (Example 38A), to create BaF3/KZ134/zcytor17m and BHK/KZ134/zcytor17m cells, respectively. The mouse OSMRbeta expression plasmid, pZP-5Z/OSMRbetam (Example 38A), was then transfected into these cells to create BaF3/KZ134/zcytor17m/OSMRbetam and BHK/KZ134/zcytor17m/OSMRbetam cell lines, respectively. Methods were as described in Example 4 with the exception that Baf3/KZ134/zcytor17m and BHK/KZ134/zcytor17m were selected with, in addition to Geneticin, 2 ug/ml puromycin while Baf3/KZ134/zcytor17m/OSMRbetam and BHK/KZ134/zcytor17m/OSMRbetam were selected with, in addition to Geneticin, 2 ug/ml puromycin and 200 ug/ml zeocin.

[0633] Clones were diluted, plated and selected using standard techniques. Clones were screened by luciferase assay (see Example 20, above) using the mouse zcytor17lig conditioned media or purified mouse zcytor17lig protein (Example 35) as an inducer. Clones with the highest luciferase response (via STAT luciferase) and the lowest background were selected. Stable transfectant cell lines were selected.

[0634] C. Mouse Zcytor17lig Activates Mouse zcytor17 Receptor in BaF3/KZ/134/zcytor17m/OSMRbetam or BHK/KZ/134/zcytor17m/OSMRbetam Luciferase Assay

[0635] Cell lines were plated for luciferase assays as described in Example 20 above. STAT activation of the BaF3/KZ134/Zcytor17m, BaF3/KZ134/zcytor17m/OSMRbetam, BHK1KZ134/zcytor17m, or BHK/KZ134/zcytor17m/OSMRbetam cells was assessed using (1) conditioned media from BHK570 cells transfected with the human zcytor17lig (Example 7), (2) conditioned media from BHK570 cells transfected with the mouse zcytor17lig (Example 18), (3) purified mouse and human zcytor17lig (Example 35), and (4) mIL-3 free media to measure media-only control response. Luciferase assays were performed as described in Example 20.

[0636] The results of this assay confirm the STAT reporter response of the BaF3/KZ134/zcytor17m/OSMRbetam and BHK/KZ134/zcytor17m/OSMRbetam cells to the mouse zcytor17lig when compared to either the BaF3/KZ134/zcytor17m cells, the BHK/KZ134/zcytor17m cells or the untransfected BaF3/KZ134 or BHK/KZ134 control cells, and show that the response is mediated through the mouse zcytor17/OSMRbeta receptors. The results also show that the human zcytor17lig does not activate the STAT reporter assay through the mouse receptor complex.

Example 39

[0637] Human zcytor17 ligand Binding to zcytor17 and zcytor17/OSMRbeta by Flow Cytometry

[0638] The biotinylation of human zcytor17L was done as follows: 100 μL of zcytor17 at 5.26 mg/mL was combined with 30 μL of 10 mg/mL EZ-link Sulfo-NHS-LC-biotin (Pierce, Rockford, Ill.) dissolved in ddH₂O. This solution was incubated on a rocker for 30 minutes at room temperature. After biotinylation the solution was dialyzed in PBS using a Slide-A-Lyzer dialysis cassette.

[0639] To test the binding properties of human zcytor17 ligand to different receptor combinations both BHK and BAF3 cells were transfected with expression plasmids using standard techniques well-known in the art. These plasmids were transfected into both cell lines in the following combinations: zcytor17 alone, OSMRbeta alone, and both zcytor17 and OSMRbeta. Transfection was performed as detailed above. Untransfected BHK and BAF3 cells were used as controls. Cells were stained by FACS as follows: 2E5 cells were stained with either: 2.0 μg/mL, 100 ng/mL, 10 ng/mL, 1.0 ng/mL, 100 pg/mL, 10 pg/mL, 1.0 pg/mL of biotinylated zcytor17L or left unstained for 30 minutes on ice in FACS buffer (PBS+2% BSA+2% NHS (Gemini)+2% NGS). Cells were washed 1.5 times and then stained with SA-PE (Jackson Immuno Laboratories) at 1:250 for 30 minutes on ice. Cells were then washed 1.5 times with FACS buffer and resuspended in FACS buffer and analyzed by FACS on a BD FACSCaliber using CellQuest software (Becton Dickinson, Mountain View, Calif.).

[0640] Both BHK and BAF3 cells showed that zcytor17 ligand bound to both zcytor17 alone and in combination with OSMRbeta with the binding to the zcytor17/OSMRbeta heterodimer being slightly stronger. No binding was seen in either cell lines expressing OSMRbeta alone. The zcytor17 ligand bound in a concentration dependent manner. The mean fluorescent intensity (MFI) values for the BHK binding are shown below in Table 15.

[0641] Gene Expression Array Analysis of Human Zcytor17lig Treated Cells

[0642] RNA was isolated from human zcytor17lig treated A549 cells, zcytor17lig treated SK-LU-1 cells, and untreated control cells using a RNeasy Midi Kit (Qiagen, Valencia, Calif.) according to the manufactures instructions.

[0643] Gene expression profiling of the cells treated with zcytor17lig and the respective control cells was carried out using GEArray Q series cDNA expression arrays (SuperArray Inc., Bethesda, Md.). The Q Series cDNA expression arrays contain up to 96 CDNA fragments associated with a specific biological pathway, or genes with similar functions or structural features. Comparison of arrays from treated and control cells allows for a determination of the up and down regulation of specific genes. Probe labeling, hybridization and detection were carried out according to the manufactures instructions. Chemiluminscent signal detection and data acquisition was carried out on a Lumi-Imager workstation (Roche, Indianapolis, Ind.). The resulting image data was analyzed using ImageQuant 5.2 (Amersham Biosciences, Inc., Piscataway, N.J.) and GEArray Analyzer 1.2 (SuperArray Inc., Bethesda, Md.) software.

[0644] Analysis of the results from the Human Interleukin and Receptor Q series HS-014N arrays, showed, after normalization, an approximate 4.7 fold increase of IL13RA2 signal in the zcytor17lig treated human SK-LU-1 cells and an approximate 2.2 fold increase of the IL13RA2 signal in the zcytor17lig treated human A549 cells.

[0645] These results indicate that zcytor17lig significantly up regulated IL13RA2 in the SK-LU-1 and A549 cells. Both of these are established cell lines derived from human lung carcinomas (Blobel et al., Virchows Arch B Cell Pathol Incl Mol Pathol., 1984;45(4):407-29). More specifically, A549 is characterized as a human pulmonary epithelial cell line (Lin, et al., J Pharm Pharmacol., September 2002; 54(9):1271-8; eMartinez et al., Toxicol Sci., October 2002; 69(2):409-23).

[0646] Interleukin-13 (IL13), a cytokine secreted by activated T lymphocytes, has been demonstrated to be both necessary and sufficient for the expression of allergic asthma and for use in experimental models of asthma, which include airway hyperresponsiveness, eosinophil recruitment, and mucus overproduction (Wills-Karp et al., Science, 1998;282:2258-2261). It has been shown, that selective neutralization of IL13 will ameliorate the asthma phenotype (Grunig et al., Science, 1998; 282:2261-2263). It has also been reported that IL13 is involved in the up regulation of mucin gene MUC8 expression in human nasal polyp epithelium and cultured nasal epithelium (Kimm et al., Acta Otolaryngol., September 2002; 122(6):638-643; Seong et al., Acta Otolaryngol., June 2002; 122(4):401-407). MUC8, a major airway mucin glycoprotein, is implicated as playing a role in the pathogenesis of mucus hypersecretion in chronic sinusitis with polps (Seong et al., Acta Otolaryngol., June 2002; 122(4):401-407).

[0647] Functionally, IL13 signals through a receptor complex consisting of the interleukin-13 receptor alpha-1 chain (IL13RA1) and IL-4 receptor alpha (IL4RA) (Daines and Hershey, J Biol Chem., 2002; 22(12):10387-10393). It has also been shown, that the interleukin-13 receptor alpha-2 (IL13RA2) binds IL13 with high affinity, but by itself (Daines and Hershey, J Biol Chem., 2002; 22(12): 10387-10393). This receptor lacks, however, the cytoplasmic domain necessary for signaling and, therefore, is considered to be a decoy receptor. It has been shown that IL13RA2 is predominately an intracellular molecule that can be quickly mobilized from intracellular stores and surface expressed following cellular treatment with interferon (IFN)-gamma. The surface expression of IL13RA2 after IFN-gamma treatment does not involve protein synthesis and results in diminished IL13 signaling (Daines and Hershey, J Biol Chem., 2002; 22(12):10387-10393).

[0648] The results of the gene expression array analysis for zcytor17lig indicate the action of zcytor17lig to be novel to that of IFN-gamma in that the zcytor17lig treatment of lung epithelial derived cell lines resulted in a significant increase of IL13RA2 gene expression. It is conceivable, therefore, that zcytor17lig treatment would be beneficial in cases where long-term up regulation of IL13RA2 expression and down regulation of IL13 is desired such as in asthma, airway hyperactivity (AHR), and mucin regulation, including chronic sinusitis with polps.

Example 41

[0649] Murine zcytor17lig Trangenic Mice

[0650] To evaluate the in vivo effects of zcytor17lig overexpression, multiple founders of transgenic mice expressing the murine form of the gene were generated, driven by two different promoters: the lymphocyte-specific promoter Eμ/lck, and the ubiquitous promoter, EF1α (Example 22). Serum protein levels range from approximately 20-300 ng/ml. The Eμ/lck promoter generated mice with higher levels of serum protein than those in the EF1α-zcytor17lig transgenic mice.

[0651] The zcytor17lig transgenic mice developed a skin phenotype around 4-8 weeks of age. The fur of the transgenic mice became “ruffled,” with obvious piloerection and mild to severe hair loss, usually on their backs, sides of the torso, and around their eyes. This phenotype was consistently found in mice with detectable levels of zcytor17lig protein in their serum. Among the founders, 100% incidence rate among the mice expressing the Eμ/lck -driven gene, and a 50% incidence in the EF1α-zcytor17lig transgenic mice was noted, correlating well with the relative levels of zcytor17lig that was detected in their serum. The transgenic skin appeared to be pruritic, as evidenced by the scratching behavior of the mice, sometimes excessive enough to induce excoriation and lesions of the skin, which usually became infected (with at least Staphylococcus aureus). The mice were originally identified with metal ear tags, but in most cases, the ear tags were forcibly removed by the mice themselves. This often resulted in severe damage to the external ear. These wounded ears often did not heal properly, as reflected in the presence of long-lasting pustules and crusting, and a seeping, expanding wound would that developed in many of the animals, behind and between their ears. Some of the transgenic mice also developed scabby wounds on their shoulders and neck. Skin lesions were observed in a subset of the animals, generally evolving on areas of skin where hair loss had already been apparent, and were often exacerbated by the scratching behavior of the mice.

[0652] RealTime quantitative RT-PCR was used to detect zcytor17lig RNA transcripts in transgenic (but not non-transgenic) skin samples, with the Eμ/lck transgenic skin expressing more zcytor17lig RNA than skin from EF1α-zcytor17lig transgenic mice. The genes encoding the zcytor17 receptor subunits, zcytor17 and OSM-Rbeta, were expressed in the skin of both non-transgenic and zcytor17lig-transgenic mice.

[0653] An examination of the lymphoid tissues from a subset of the Eμ/lck-transgenic founders by flow cytometry revealed a significant increase in the proportion of activated T cells in the spleen and lymph nodes of these mice. Two of the four mice analyzed had severely enlarged-cervical lymph nodes, possibly due to the presence of lesions on their necks. A subtle increase in spleen weight and a slight increase in monocytes and neutrophils circulating in the blood of the transgenic mice was observed. There was no increase in a variety of cytokines tested, nor were there changes in the circulating serum amyloid A levels in these mice. The effects on the immune cells in the transgenic mice may be a direct or an indirect result of zcytor17lig, or are secondary effects of the skin lesions.

[0654] Histopathology was performed on many tissues other than skin, including liver, thymus, spleen, kidney, and testes, and no significant abnormalities in these organs were noted. Analysis of the transgenic skin, however, did reveal a number of alterations, which varied greatly depending upon the source and location of skin (e.g., normal, hairless, or lesional). In many cases, the ears of the transgenic mice had a thickened epidermis as compared to the non-transgenic controls (e.g., approximately 4 layers versus 2 layers), and the underlying tissues contained low to moderate numbers of inflammatory cells, which were primarily mononuclear with occasional neutrophils. The epidermis over the abdomen appeared multifocally slightly thicker in the transgenic, but there was no apparent increase in inflammatory cells in the underlying dermis or subcutis. In the hairless portions of skin from these mice, there were dilated hair follicles that contained some debris but no hair shafts (e.g., the hairs fell out by the roots). In the lesioned areas, there was severe thickening of the epidermis (acanthosis), increased keratin on the surface of the skin (hyperkeratosis), scattered ulcers of varying size and significant numbers of inflammatory cells in the dermis (mainly neutrophils, with varying numbers of macrophages and lymphocytes). The dermis also contained numerous mast cells bordering the lesions. Some of the hair shafts in the lesioned areas of the transgenic skin were in the active stage (anagen), in contrast to many of the hair shafts in “normal” areas which were in the involuting (catagen) to inactive (telogen) stage.

[0655] The phenotype of the zcytor17lig transgenic mice strongly resembles that of atopic dermatitis (AD) patients, and mouse models of AD. AD is a common chronic inflammatory disease that is characterized by hyperactivated cytokines of the helper T cell subset 2 (Th2). Zcytor17lig is preferentially expressed by Th2 vs. Th1 cells, which lends further credence to this comparison. Although the exact etiology of AD is unknown, multiple factors have been implicated, including hyperactive Th2 immune responses, autoimmunity, infection, allergens, and genetic predisposition. Key features of the disease include xerosis (dryness of the skin), pruritus (itchiness of the skin), conjunctivitis, inflammatory skin lesions, Staphylococcus aureus infection, elevated blood eosinophilia, elevation of serum IgE and IgG1, and chronic dermatitis with T cell, mast cell, macrophage and eosinophil infiltration. Colonization or infection with S. aureus has been recognized to exacerbate AD and perpetuate chronicity of this skin disease.

[0656] AD is often found in patients with asthma and allergic rhinitis, and is frequently the initial manifestation of allergic disease. About 20% of the population in Western countries suffer from these allergic diseases, and the incidence of AD in developed countries is rising for unknown reasons. AD typically begins in childhood and can often persist through adolescence into adulthood. Current treatments for AD include topical corticosteroids, oral cyclosporin A, non-corticosteroid immunosuppressants such as tacrolimus (FK506 in ointment form), and interferon-gamma. Despite the variety of treatments for AD, many patients' symptoms do not improve, or they have adverse reactions to medications, requiring the search for other, more effective therapeutic agents.

[0657] Epithelial cells, which express the heterodimeric receptor for zcytor17lig (zcytoR17 and OSM-Rbeta), are located at the sites (e.g., skin, gut, lung, etc.) of allergen entry into the body and interact closely with dendritic cells (professional antigen presenting cells) in situ. Dendritic cells play an important role in the pathogenesis of allergic diseases, and it is possible that zcytor17lig can interact with its receptor on epithelial cells in the skin and lung and influence immune responses in these organs. Zcytor17lig and its receptor(s) may therefore contribute to the pathogenesis of allergic diseases such as AD and asthma. Furthermore, the phenotype of the zcytor17lig transgenic mice suggests that this ligand may play a role in wound healing, since the mice seem unable to repair damage to their ears, and often bear long-lasting lesions on their backs and sides. An antagonist of zcytor17lig might therefore represent a viable therapeutic for these and other indications.

[0658] Luciferase Assay on Human Transformed Epithelial Cell Lines via Transient Infection with an Adenoviral STATISRE Reporter Gene

[0659] A wide variety of human transformed epithelial cell lines (see Table 16 below) were seeded in 96-well flat-bottom plates at 10,000 cell/well in regular growth media as specified for each cell type. The following day, the cells were infected with an adenovirus reporter construct, KZ136, at a multiplicity of infection of 5000. The KZ136 reporter contains the STAT elements in addition to a serum response element. The total volume was 100 ul/well using DMEM supplemented with 2 mM L-glutamine (GibcoBRL), 1 mM Sodium Pyruvate (GibcoBRL) and 1×Insulin-Transferrin-Selenium supplement (GibcoBRL) (hereinafter referred to as serum-free media). Cells were cultured overnight.

[0660] The following day, the media was removed and replaced with 100 μl of induction media. The induction media was human zcytor17 ligand diluted in serum-free media at 100 ng/ml, 50 ng/ml, 25 ng/ml, 12.5 ng/ml, 6.25 ng/ml, 3.125 ng/ml and 1.56 ng/ml. A positive control of 20% FBS was used to validate the assay and to ensure the infection by adenovirus was successful. The cells were induced for 5 hours at which time the media was aspirated. The cells were then washed in 50 μl/well of PBS, and subsequently lysed in 30 μl/well of 1×cell lysis buffer (Promega). After a 10-minute incubation at room temperature, 25 μl/well of lysate was transferred to opaque white 96-well plates. The plates were then read on the Luminometer using 5-second integration with 40 μl/well injection of luciferase substrate (Promega).

[0661] The results revealed the ability of multiple epithelial cell lines to respond to zcytor17 ligand as shown in Table 16 below.

[0662] Cytokine Production by Human Epithelial Cell Lines Cultured with Human zcytor17 Ligand

[0663] Human disease-state epithelial cell lines (A549, human lung epithelial carcinoma; SkLu1, human lung epithelial adenocarcinoma; DU145, human prostate epithelial carcinoma; PZ-HPV-7, human prostate epithelial HPV transformed; U20S, human bone epithelial osteosarcoma) were screened for cytokine production in response to zcytor17 ligand in vitro. These cell lines have both zcytor17 and OSMR-beta, identified by RT-PCR, and respond to human zcytor17 ligand when assayed with the adenoviral luciferase reporter construct, KZ136 (Example 42). Cytokine production by these cell lines was determined in response to human zcytor17 ligand in a series of three experiments.

[0664] A. Cytokine Production by Human Disease-State Epithelial Cell Lines Cultured with Human zcytor17lig

[0665] Cells were plated at a density of 4.5×10⁵ cells per well in a 6 well plate (Costar) and cultured in respective growth media. The cells were cultured with test reagents; 100 ng/mL zcytor17 ligand, 10 ng/mL Interferon gamma (IFN gamma) (R&D Systems, Minneapolis, Minn.), 10 ng/mL Tumor Necrosis Factor alpha (TNF alpha) (R&D Systems, Minneapolis, Minn.), 10 ng/mL IL-1beta (R&D Systems, Minneapolis, Minn.) or 100 ug/mL Lipopolysaccharide (LPS) (Sigma). Supernatants were harvested at 24 and 48 hours and assayed for cytokines; GM-CSF (Granulocyte-Macrophage Colony-Stimulating Factor), IL-1b, IL-6, IL-8, MCP-1 (Macrophage Chemoattractant Protein-1) and TNFa. Multiplex Antibody Bead kits from BioSource International (Camarillo, Calif.) were used to measure cytokines in samples. Assays were read on a Luminex-100 instrument (Luminex, Austin, Tex.) and data was analyzed using MasterPlex software (MiraiBio, Alameda, Calif.). Cytokine production (pg/mL) for each cell line in the 24-hour samples is shown below in Table 17.

[0666] All cell lines tested produced GM-CSF and IL-8 in response to stimulation with control cytokines IL-1b and TNFa. Most cell lines produced IL-6 and MCP-1in response to IL-1b and TNFa stimulation. Zcytor17 ligand stimulated IL-6 production in the DU145 cell line compared to control (193 pg/mL vs. 71 pg/mL). Zcytor17 ligand stimulated 3 of 5 cell lines to produce IL-8 with the greatest effect seen in A549 cells (5 fold), and reduced IL-8 production in U2OS cells by 2 fold. There was a slight effect on MCP-1 production by DU145 and U2OS cells when cultured with zcytor17 ligand.

[0667] B. Cytokine Production by Normal Human Epithelial Cell Lines Cultured with Human zcytor17lig

[0668] In addition to the human epithelial cell lines, normal human bronchial epithelial cells (NUBE, Clonetics) were also tested. Cells were plated at a density of 1×10⁵ cells per well in a 24 well plate and cultured with test reagents; 1000 ng/mL, 100 ng/mL and 10 ng/mL zcytor17 ligand (A760F), 10 ng/mL TNFa, 10 ng/mL OSM, 10 ng/mL IFNa, 10 ng/mL TGFb or 10 ng/mL Lymphotactin. Supernatants were harvested at 24 and 48 hours and assayed for cytokines; IL-6, IL-8, MCP-1, MIP-1a, RANTES and Eotaxin. Cytokines were assayed as previously described. Cytokine production (pg/mL) for each cell line in the 48-hour samples is shown below in Table 18. TABLE 18 A549 DU145 SkLu1 U2OS NHBE IL-6 pg/ml r17L 1000 ng/ml 24.5 56.3 32.1 25.2 64.5 r171L 100 ng/ml 25.0 65.0 31.0 25.4 50.2 r17L 10 ng/ml 24.8 51.8 30.2 25.3 54.3 TNFa 272.9 355.4 437.5 36.1 299.3 OSM 26.4 73.5 112.4 25.6 80.4 IFNa 24.6 109.3 33.7 26.4 52.4 TGFb 24.4 102.6 42.7 27.8 268.9 control 24.5 36.3 29.9 25.2 47.9 IL-8 pg/ml r17L 1000 ng/ml 35.0 243.3 45.6 18.6 402.0 r171L 100 ng/ml 31.0 290.7 40.1 21.3 296.0 r17L 10 ng/ml 30.4 240.4 33.4 18.9 361.8 TNFa 2809.3 2520.9 1385.2 784.9 1486.3 OSM 37.8 60.6 68.0 22.5 494.6 IFNa 18.9 315.3 39.5 33.1 231.6 TGFb 9.9 77.5 19.6 88.9 246.9 control 10.9 238.0 38.0 39.7 315.8 MCP-1 pg/ml r17L 1000 ng/ml nd nd 149.1 81.0 nd r171L 100 ng/ml nd nd 130.6 81.9 nd r17L 10 ng/ml nd nd 111.7 49.1 nd TNFa nd 22.1 2862.6 1104.7 nd OSM nd 17.2 448.2 85.8 nd IFNa nd nd 131.7 10.5 nd TGFb nd 1.7 54.5 27.6 nd control nd nd 113.0 1.7 nd

[0669] DU145 cells produced IL-6 in response to zcytor17 ligand, repeating the previous results in Example 43A. However, only A549 and U2OS had similar IL-8 responses as seen Example 43A. SkLu1 and U2OS cells both produced MCP-1 in response to zcytor17 ligand. Cytokine production by NHBE cells was marginal compared to controls.

[0670] C. Cytokine Production by Human Disease-State Epithelial Cell Lines Co-Cultured with Human zcytor17lig and IFN Gamma

[0671] Cells were plated at a density of 2×10⁵ cells per well in 24 well plate and co-cultured with 10 ng/mL IFN gamma±zcytor17 ligand at 100 ng/mL, 10 ng/mL or 1 ng/mL. Supernatants were collected at 24 and 48 hours and assayed for IL-8 and MCP-1 as described above. Cytokine production (pg/mL) for each cell line in the 24-hour samples is shown below in Table 19. TABLE 19 IL-8 pg/ml MCP-1 pg/ml A549 10 ng/mL IFNg + 100 ng/mL r17L 86.7 nd 10 ng/mL IFNg + 10 ng/mL r17L 75.1 nd 10 ng/mL IFNg + 1 ng/mL r17L 63.6 nd 10 ng/mL IFNg 35.4 nd control 36.6 nd DU145 10 ng/mL IFNg + 100 ng/mL r17L 102.3 nd 10 ng/mL IFNg + 10 ng/mL r17L 92.9 nd 10 ng/mL IFNg + 1 ng/mL r17L 79.9 nd 10 ng/mL IFNg 70.7 nd control 79.4 nd SkLu1 10 ng/mL IFNg + 100 ng/mL r17L 152.2 604.9 10 ng/mL IFNg + 10 ng/mL r17L 194.4 870.7 10 ng/mL IFNg + 1 ng/mL r17L 138.7 585.4 10 ng/mL IFNg 170.8 652.6 control 203.0 292.3 U2OS 10 ng/mL IFNg + 100 ng/mL r17L 106.8 357.0 10 ng/mL IFNg + 10 ng/mL r17L 108.2 347.7 10 ng/mL IFNg + 1 ng/mL r17L 109.9 293.3 10 ng/mL IFNg 118.8 159.8 control 146.8 7.0

[0672] A549 cells produced IL-8 in response to zcytor17 ligand, however there was no effect of co-culturing cells with the addition of IFN gamma. U2OS cells made 20 fold more MCP-1 when cultured with IFNg and 50 fold more MCP-1 when cultured with IFN gamma+zcytor17 ligand.

Example 44

[0673] Zcytor17lig Effects on ³H-TdR Incorporation in DU145 Prostate Epithelial Carcinoma Cells

[0674] Cells were seeded in 96-well tissue clusters (Falcon) at a density of 25,000/well in MEM (Life Technologies) growth medium supplemented with glutamine, pyruvate, non-essential amino acids (Life Technologies) and 10% fetal bovine serum (Hyclone). At confluence (24 hours later), cells were switched to growth arrest media by substituting 0.1% BSA (Life Technologies) for serum. After 48 hours to achieve cell synchronization, the growth-arrest medium was replaced with fresh medium. Then, human recombinant zcytor17lig (test reagent) was added at various concentrations (from 0.24 to 60 ng/mL) (see Table 16 below), to test for the effect of the protein on basal DNA replication. Some wells received 2.5% FBS (Hyclone) in addition to zcytor17Ligand, in order to test effect of the protein on elevated levels of TdR incorporation. FBS 10% and 20 ng/ml Platelet Derived Growth Factor-BB (PDGF-BB) (R&D) were used as positive control.

[0675] Eighteen hours following addition of zcytor17Ligand and the rest of the test reagents, cells were pulsed with 250 nCi/mL [³H]-thymidine (NEN) for 4 hours. Following the 4-hour pulse, media were discarded and 100 μL trypsin solution (Life Technologies) was added in each well to dislodge the cells. The radioactivity incorporated by DU145 was determined by harvesting the cells with a Packard Filtermate 196 cell harvester and by counting the incorporated label using a Packard TopCount NXT microplate scintillation counter.

[0676] As can be seen in Table 20 below, zcytor17lig induced thymidine incorporation in quiescent cells (in 0.1% BSA) in a concentration-dependent manner. This effect reached 2.5-fold of the BSA control at the highest concentration used, 60 ng/mL. In addition, this effect of zcytor17lig was also detectable when the baseline incorporation was elevated by the addition of 2.5% FBS (in this series as potent a mitogen as 10% FBS). These results therefore indicate that under both basal and stimulated conditions zcytor17lig can act as a mitogenic factor for the DU145 carcinoma cells.

[0677] Table 16 shows the effects of zcytor17lig on thymidine incorporation by DU145 cells. Results are expressed in cpm/well and numbers are the mean±st.dev of triplicate wells.

[0678] Expression of huzcytor17Ligand in E. coli

[0679] A. Construction of Expression Vector pRPSO1 that Expresses huzcytor17Lig/MBP-6H Fusion Polypeptide

[0680] An expression plasmid containing a polynucleotide encoding a huzcytor17lig fused C-terminally to Maltose Binding Protein (MBP) was constructed via homologous recombination. The fusion polypeptide contains an N-terminal approximately 388 amino acid MBP portion fused to the huzcytor17Lig described herein. A fragment of huzcytor17lig cDNA was isolated using the PCR method as described herein. Two primers were used in the production of the zcytor17lig fragment in a standard PCR reaction: (1) one containing 40 bp of the vector flanking sequence and 20 bp corresponding to the amino terminus of the huzcytor17lig, and (2) another containing 40 bp of the 3′ end corresponding to the flanking vector sequence and 20 bp corresponding to the carboxyl terminus of the huzcytor17lig. Two microliters of the 100 μl PCR reaction was run on a 1.0% agarose gel with 1×TBE buffer for analysis, and the expected molecular weight fragment was observed. The remaining PCR reaction was combined with the second PCR tube and precipitated with 400 μL of absolute ethanol. The precipitated DNA was used for recombination into the Sma1 cut recipient vector pTAP98 to produce the construct encoding the MBP-huzcytor17lig fusion, as described below.

[0681] The vector pTAP98 was constructed using yeast homologous recombination. One hundred nanograms of EcoR1 cut pMAL-c2 was recombined with 1 μg Pvu1 cut pRS316, 1 μg linker, and 1 μg Sca1/EcoR1 cut pRS316 were combined in a PCR reaction. PCR products were concentrated via 100% ethanol precipitation. The competent yeast cell (S. cerevisiae) strain, SF838-9Dα, was combined with 10 μl of a lo mixture containing approximately 1 μg of the huzcytor17lig PCR product (above) and 100 ng of SmaI digested pTAP98 vector, and electroporated at 0.75 kV, 25 μF and ∞ ohms. The resulting reaction mixture was plated onto URA-D plates and incubated at 30° C.

[0682] After 48 hours, the Ura+ yeast transformants from a single plate were selected. DNA was isolated and transformed into electrocompetent E. coli cells (e.g., MC1061, Casadaban et. al. J. Mol. Biol. 138, 179-207). The resulting E. coli cells were plated on MM/CA+AMP 100 mg/L plates (Pryor and Leiting, Protein Expression and Purification 10:309-319, 1997) using standard procedures. Four individual clones were harvested from the plates and inoculated into MM/CA with 100 μg/ml Ampicillin for two hours at 37° C. One milliliter of each of the culture was induced with 1 mM IPTG. Approximately 2-4 hours later, 250 μl of each induced culture was mixed with 250 μl acid washed glass beads and 250 μl Thorner buffer with 5% βME and dye (8M urea, 100 mM Tris pH7.0, 10% glycerol, 2 mM EDTA, 5% SDS). Samples were vortexed for one minute and heated to 65° C. for 10 minutes. Twenty microliters of each sample was loaded per lane on a 4% -12% PAGE gel (NOVEX). Gels were run in 1×MES buffer. The positive clones were designated pRPSOI and subjected to sequence analysis.

[0683] One microliter of sequencing DNA was used to transform electrocompetent E. coli cell strain MC1061. The cells were electropulsed at 2.0 kV, 25 μF and 400 ohms. Following electroporation, cells were rescued 0.6 ml SOC and grown on LB+Amp plates at 37° C. overnight, with 100 mg/L Ampicillin. Four cultures were induced with ITPG and screened for positives as described above. The positive clones were expanded for protein purification of the huzcytor17lig/MBP-6H fusion protein using standard techniques.

[0684] B. Purification of huzcytor17Lig/MBP-6H from E. coli Fermentation

[0685] Unless otherwise noted, all operations were carried out at 4° C. The following procedure was used to purify recombinant huzcytor17Lig/MBP-6H polypeptide. E. coli cells containing the pRPSO1 construct and expressing huzcytor17Lig/MBP-6H, were constructed using standard molecular biology methods and cultured in 50.0 g/L SuperBroth II (12 g/L Casien, 24 g/L Yeast Extract, 11.4 g/L di-potassium phosphate, 1.7 g/L Mono-potassium phosphate; Becton Dickenson, Cockeysville, Md.), 5 g/L glycerol and 5 mL/L 1M Magnesium Sulfate. Twenty grams of cells were harvested and frozen for protein purification.

[0686] The thawed cells were resuspended in 500 mL Amylose Equilibration buffer (20 mM Tris, 100 mM NaCl, pH 8.0). A French Press cell breaking system (Constant Systems Ltd., Warwick, UK) with a temperature setting of −7° C. to −10° C. and 30K PSI was used to lyse the cells. The resuspended cells were assayed for breakage by A₆₀₀ readings before and after cycling through the French Press. The processed cell suspension was pelleted at 10,000G for 30 minutes to remove the cellular debris and the supernatant was harvested for protein purification.

[0687] A 25 ml column of Amylose resin (New England Biolabs, Beverly, Mass.) (prepared as described below) was poured into a Bio-Rad, 2.5 cm D×10 cm H glass column. The column was packed and equilibrated by gravity with 10 column volumes (CVs) of Amylose Equilibration buffer. The processed cell supernatant was batch loaded to the Amylose resin overnight, with rocking. The resin was returned to the Bio-Rad column and washed with 10 CV's of Amylose Equilibration buffer by gravity. The column was eluted with ˜2 CV of Amylose Elution buffer (Amylose Equilibration buffer+10 mM Maltose, Fluka Biochemical, Switzerland) by gravity. Ten 5 mL fractions were collected over the elution profile and assayed for Absorbance at 280 and 320 nM. The Amylose resin was regenerated with 1 CV of distilled H₂O, 5 CVs of 0.1% (w/v) SDS (Sigma), 5 CVs of distilled H₂O, 5 CVs of Amylose Equilibration buffer and finally 1 CV of Amylose Storage buffer (Amylose Equilibration buffer+0.02% Sodium Azide). The regenerated column was stored at 4° C.

[0688] Elution profile fractions of interest were pooled and dialyzed in a 10K dialysis chamber (Slide-A-Lyzer, Pierce Immunochemicals) against 4×4L PBS pH 7.4 (Sigma) over an 8 hour time period to remove low molecular weight contaminants, buffer exchange and desalt. Following dialysis, the material harvested represented the purified huzcytor17Lig/MBP-6H polypeptide. The purified huzcytor17Lig/MBP-6H polypeptide was filter sterilized and analyzed via SDS-PAGE Coomassie staining for an appropriate molecular weight product. The concentration of the huzcytor17Lig/MBP-6H polypeptide was determined by BCA analysis to be 1.28 mg/mL.

[0689] Human zcytor17lig Polyclonal Antibody

[0690] A. Preparation and Purification

[0691] Polyclonal antibodies were prepared by immunizing 2 female New Zealand white rabbits with the purified recombinant protein hzcytor17L/MBP-6H (Example 45). The rabbits were each given an initial intraperitoneal (IP) injection of 200 μg of purified protein in Complete Freund's Adjuvant followed by booster IP injections of 100 μg protein in Incomplete Freund's Adjuvant every three weeks. Seven to ten days after the administration of the second booster injection (3 total injections), the animals were bled and the serum was collected. The animals were then boosted and bled every three weeks.

[0692] The hzcytor17L/MBP-6H specific rabbit serum was pre-adsorbed of anti-MBP antibodies using a CNBr-SEPHAROSE 4B protein column (Pharmacia LKB) that was prepared using 10 mg of non-specific purified recombinant MBP-fusion protein per gram of CNBr-SEPHAROSE. The hzcytor17L/MBP-6H-specific polyclonal antibodies were affinity purified from the pre-adsorbed rabbit serum using a CNBr-SEPHAROSE 4B protein column (Pharmacia LKB) that was prepared using 10 mg of the specific antigen purified recombinant protein hzcytor17L/MBP-6H. Following purification, the polyclonal antibodies were dialyzed with 4 changes of 20 times the antibody volume of PBS over a time period of at least 8 hours. Hzcytor17-Ligand-specific antibodies were characterized by ELISA using 500 ng/ml of the purified recombinant proteins hzcytor17L/MBP-6H or hzcytor17L-CEE produced in a baculovirus expression system as antibody targets. The lower limit of detection (LLD) of the rabbit anti-hzcytor17L/MBP-6H affinity purified antibody is 100 pg/ml on its specific purified recombinant antigen hzcytor17L/MBP-6H and 500 pg/ml on purified recombinant hzcytor17L-CEE produced in a baculovirus expression system.

[0693] B. SDS-PAGE and Western Blotting Analysis of Rabbit Anti-Human ZcytoR17lig MBP-6H Antibody

[0694] Rabbit Anti-human ZcytoR17lig MBP-6H antibody was tested by SDS-PAGE (NuPage 4-12% , Invitrogen, Carlsbad, Calif.) with coomassie staining method and Western blotting using goat anti-rabbit IgG-HRP. Human and mouse zcytor17lig purified protein (200-25 ng) was electrophoresed using an Invitrogen Novex's Xcell II mini-cell, and transferred to nitrocellulose (0.2 mm; Invitrogen, Carlsbad, Calif.) at room temperature using Novex's Xcell blot module with stirring according to directions provided in the instrument manual. The transfer was run at 300 mA for one hour in a buffer containing 25 mM Tris base, 200 mM glycine, and 20% methanol. The filter was then blocked with Western A buffer (in house, 50 mM Tris, pH 7.4, 5 mM EDTA, pH 8.0, 0.05% Igepal CA-630, 150 mM NaCl, and 0.25% gelatin) overnight with gentle rocking at 4° C. The nitrocellulose was quickly rinsed, then the rabbit anti-human zcytoR17lig MBP-6H (1:1000) was added in Western A buffer. The blot was incubated for 1.5 hours at room temperature with gentle rocking. The blot was rinsed 3 times for 5 minutes each in Western A, then goat anti-rabbit IgG HRP antibody (1:5000) was added in Western A buffer. The blot was incubated for 1 hour at room temperature with gentle rocking. The blot was rinsed 3 times for 5 minutes each in Western A, then quickly rinsed in H₂O. The blot was developed using commercially available chemiluminscent substrate reagents (ECLWestern blotting detection reagents 1 and 2 mixed 1:1; reagents obtained from Amersham Pharmacia Biotech, Buckinghamshire, England) and the blot was exposed to x-ray film for up to 5 minutes.

[0695] The purified human zcytor17lig appeared as a large band at about 30 kDa and a smaller band at about 20 kDa under reduced conditions. The mouse zcytor17lig was not detected by the rabbit anti-human zcytor17lig antibody.

[0696] Zcytor17lig Effects on U937 Monocyte Adhesion to Transformed Bone Marrow Endothelial Cell (TRBMEC) Monolayer

[0697] Transformed Bone Marrow Endothelial Cells (TRBMEC) were seeded in 96-well tissue clusters (Falcon) at a density of 25,000/well in medium M131 (Cascade Biologics) supplemented with Microvascular Growth Supplement (MVGS) (Cascade Biologics). At confluence (24 hours later), cells were switched to M199 (Gibco-Life Technologies) supplemented with 1% Fetal Bovine Serum (Hyclone). Human recombinant zcytor17lig (test reagent) was added at various concentrations (from 0.4 to 10 ng/mL) (see Table 21 below), to test for the effect of the protein on immune cell-endothelial cell interactions resulting in adhesion. Some wells received 0.3 ng/ml Tumor Necrosis Factor (TNFalpha R&D Systems), a known pro-inflammatory cytokine, in addition to zcytor17lig, to test an effect of the protein on endothelial cells under inflammatory conditions. TNFalpha at 0.3 ng/ml alone was used as positive control and the concentration used represents approximately 70% of the maximal TNFalpha effect in this system, i.e., it does not induce maximal adherence of U937 cells (a human monocyte-like cell line) to the endothelium. For this reason, this setup can detect both upregulation and downregulation of the TNFalpha effects. Basal levels of adhesion both with and without TNFalpha were used as baseline to assess effect of test reagents.

[0698] After overnight incubation of the endothelial cells with the test reagents (zcytor17ligand±TNFalpha), U937 cells, stained with 5 μM Calcein-AM fluorescent marker (Molecular Probes), the cells were suspended in RPMI 1640 (no phenol-red) supplemented with 1% FBS and plated at 100,000 cells/well on the rinsed TRBMEC monolayer. Fluorescence levels at excitation/emission wavelengths of 485/538 nm (Molecular Devices micro-plate reader, CytoFluor application) were measured 30 minutes later, before and after rinsing the well three times with warm RPMI 1640 (no phenol-red), to remove non-adherent U937. Pre-rinse (total) and post-rinse (adherence-specific) fluorescence levels were used to determine percent adherence (net adherent/net total×100=% adherence).

[0699] As can be seen in Table 21 below, zcytor17lig when added alone affected the basal adherence of U937 cells to the endothelial monolayers at the concentration range used (less than 2-fold increases, p<0.01 by ANOVA test). By itself, the positive control, 0.3 ng/mL TNFalpha, increased the adherence of U937 cells from a basal 5.8% to 35% (6-fold). In the presence of TNFalpha, zcytor17lig synergized with TNFalpha and further enhanced U937 adhesion in a concentration-dependent manner between 0.4 and 10 ng/mL (p<0.01 by ANOVA test). At 10 ng/mL, zcytor17lig enhanced the effect of TNFalpha by 62% . These results indicate that zcytor17lig may by itself be a pro-inflammatory agent. Zcytor17lig was able to synergize with sub-maximal concentrations of TNFalpha to increase monocyte adherence to endothelial cells. These results also show that endothelial cells, especially when exposed to pro-inflammatory cytokines such as TNFalpha, are a likely target tissue of zcytor17lig action. The consequence of zcytor17ligand on endothelial cells may be to heighten monocyte or macrophage adhesion to a site of proinflammatory activity. Activated monocytes and macrophages are important in many inflammatory diseases. Therefore inhibition of monocyte/macrophage adhesions may provide a therapeutic rationale for zcytor17ligand antagonists. This data would support the use of zcytor17 ligand antagonists for treatment lung diseases, vascular diseases, autoimmunity, tumor metastasis, disease involving allergic reactions, wound healing and diseases of the skin including contact, allergic or non-allergic dermatistic or psoriasis and inflammatory bowel disease. Table 21 shows the effects of zcytor17lig on U937 monocyte adhesion to TRBMEC endothelial monolayers. Results are expressed in percent adhesion and numbers are the mean±st.dev of triplicate wells.
